3:6 Parvaim is not mentioned elsewhere in Scripture. This fact alone should make us realise that the record was written at the time of the events it records. Parvaim was clearly a location known to the people in the time of Solomon.

4:2 The molten sea did not have any counterpart in the tabernacle. This 'sea' was for the washing of the priests. The laver was for the washing of the animals that were to be sacrificed and answered to the similar vessel in the tabernacle.
We have to conclude that the molten sea described here was part of the pattern that God gave him to follow.

3:1 Mount Moriah was the place where Abraham offered Isaac ad the place of the threshingfloor of Arunah the Jebusite (2 Samuel 24:16). The earlier events mentioned provided the explanation as to where the temple was to be built.

4:1 The altar of brass Solomon made is four times as big as the one that was made in the wilderness (Exodus 27:1). The absence of other details in addition to it's size might mean that the details given in Exodus would form the basis for it's manufacture. Or maybe the absence of mention of stave to carry it were to indicate that the altar was now in a permanent resting place.

3:3 Notice that Solomon was 'instructed' in matters relating to the building of the house. David received a 'pattern' (1 Chronicles 28:11, 12, 18,19) so clearly he did more than just pass the pattern on to Solomon. He spoke with him about how to do the work as well.

4:11 Huram's involvement in manufacturing the furniture for the tabernacle foreshadows the inclusion on the gentiles (you and I) in the living temple - the church of the living God. The fulfilment of the promise to David that He would build him an house' (2 Samuel 7:27)

3:2 So Solomon reigned for three years before beginning to build the temple. This might seem rather slow given that David had already prepared the materials (1Chron 22:14) and the plans were already available (1Chron 28:11). However we should realise that Solomon was establishing the kingdom and developing a settled situation in which the temple was to be built.

4 The detailed description of the way that things were made for the temple focus, not on the outward structure of the building, but on the various items used in service to God. This highlights to us it is not outward appearance that matters - even though the temple was 'exceeding magnifical' (1Chron 22:5)  - but rather the way that worship is shown is more important.

Solomon made 2 huge cherubim to go inside the Most Holy Place. Their wings touched in the centre, and altogether were 20 cubits or 30 feet long, touching the wall at either end (2Chron 3:10-13).  The ark of the covenant (Exo 25:10), which was only 2 ½ cubits long (= less than 4 feet long), was to be stood in front of these 2 wonderful cherubim (see 2Chron 5:7).

3:13 When we read that the feet and faces were ‘inward’ we should understand this as being ‘towards the house’.

4:2-4 The sea contained water and rested upon oxen. This is symbolic of the work of God’s servants. Water equates with the Scriptures – Eph 5:26 – The oxen speak of service. The servants uphold the water of life in their preaching.

3:1 It is supposed that Mount Moriah is the place where Abraham was ready to sacrifice Isaac as a burnt offering (Gen 22:2).  However, it is unclear whether the land of Moriah is referring to Mount Moriah. 

Nevertheless, the spiritual connection between the site of the temple and Isaac's sacrifice is strong.  Yahweh, having been pleased with the faith of Abraham, spared Isaac.  He said that He would provide a lamb (Gen 22:8).  That lamb was Jesus. 

The temple is where Yahweh placed His Name (1Kin 8:29).  The temple was built on Mount Moriah.  Jesus is the spiritual temple (Matt 26:61). All true believers of Jesus are part of that temple (1Cor 3:16).

3:1 David had ‘appointed’ RV the place where the temple was to be built further reinforcing the point that David had done the planning and the place was specifically chosen by David.

3:1 The items that Solomon made for the temple according to the pattern that David had indicates that the items made were ‘of God’ though there is no command given – such as in Exo 25 - Exo 27 regarding the furniture of the Tabernacle - that these things should be made.

2Chron 3:5 - "greater house" refers to the Holy Place or main chamber of the temple.

2Chron 3:11-12;2Chron 4:2,6-8 - numerous mentions of  "5" thought by some to suggest "mercy, (or) grace". 2Chron 4:4-5 - several mentions of  "3" thought by some to suggest "divine perfection, (or) sacrifice (and/or) resurrection".

2Chron 3:16;2Chron 4:13 - our sacrificed redeemer is like the red pomegranate packed with seed and so he shall redeem many unto eternal life.

2Chron 3:17 - the pillars "Jachin" and "Boaz" were at the entrance - could they represent/foreshadow Jew and Gentile seeking entrance to the future earthly kingdom through Christ?

40:6 In being taken to the "gate  which looketh toward the east" Ezekiel is arriving at the city in the direction that the glory of God left the city (Eze 9:9) and will return (Eze 43:4).

V.46 Zadok was of the line from Aaron. He had the high priesthood confered on him Solomon, who had set aside the family of Ithamar, because of the part which Abiathar had taken in the rebellion of Adonijah. (1Kin 1:7, 1Kin 2:26-27)

There is critical information here that we do well to recognize in order to best interpret the later chapters in the propecy (i.e. chapter 44). 
Two Classes of Priests are introduced here with distinction. Both are Levitical priest, but the first, are "keepers of the charge of the house" and correspond to chater 44:10-14, and 17 onwards.
The second class are "keepers of the charge of the altar"- Eze 40:45,46 and correspond to Chapter 44:15,16.
Later we will learn why the distiction was made due to past practice. Malachi 2 will suffice to show the failure of the priesthood in keeping the commandments. Those who didn't go astray, will be resurrected to immortality along with the other faithful making up the Sons of Zadok(righteousness) class after the order which is established in the King, Christ(Melchizadok order).

40:3 The idea of a measuring reed is taken up in Zech 2:1  – surely an encouragement after the exile to the people to think of the return as a fulfilment of the things that Ezekiel saw.

40:46 In saying that the "sons of Zadok" will have a particular task to do we have to conclude that in the kingdom the exact part of a tribe from which a man descends will be know. This will be achieved by Jesus – Mal 3:3 – who will ‘purge the sons of Levi’, that is establish their lineage.

40:2 Here Ezekiel sees ‘the frame of a city’ and what he sees is a glorious picture which contrasts with the evil that he sees in the city – Eze 8:3

V.1 etc. The details of the temple start in this chapter and continue until the end of the Book of Ezekiel. The Jews in exile would have been encouraged that a new temple was to be built.  But no temple was built in their lifetimes. 

And so, the temple described here would have been taken to mean one that would be built when the Messiah came.  The dimensions of this temple do not relate to the refurbished second temple of Herod the Great. That temple was destroyed in 70 AD by the Romans. 

Today, religious Jews are waiting for their Messiah to appear and for a third temple to be built. That will happen after Jesus returns to the earth, and is recognized by the Jews as their Messiah.

Beware of religious commentators who think that Ezekiel's temple is a metaphor for orderly spiritual living. These commentators do not believe that Jesus is coming back to earth to set up His kingdom in which the inhabitants will learn of Yahweh's ways.  

These commentators believe, erroneously, in a reward in which souls go to heaven at death.  With that belief one would be hard pressed to believe that Ezekiel's temple would be a real building on earth. 

But, the Bible says that the reward of the faithful followers of Jesus is on earth (Rev 22:12). Those who are rewarded will serve as priests in the kingdom (Rev 1:6; 5:10).  And what would priests be without a temple?

40:4 In seeing with his eyes and haring with his ears Ezekiel is very unlike those who captivity war prophesied because they would not here or see – Isa 6:10

Sir Isaac Newton, the famous scientist who discovered gravity and documented the three laws of physics, also studied prophecy. One of his treasured subjects was the temple. His writing on this chapter can be found in Manuscript 434 at this link, where you will find his drawing of the gateway:

http://www.newtonproject.sussex.ac.uk/view/texts/normalized/THEM00079

I've imported a scan of his drawing and scaled it, making up for some skewing, and have come up with the following dimensions. It appears to fit very well, and given Sir Isaac's authority I would tend to go with his findings:

40:2 In setting Ezekiel upon a ‘very high mountain’ we see the pattern of the way in which God showed John – Rev 21:10 – the ‘holy Jerusalem’. Whilst Ezekiel saw a pattern of a real temple that will be built as a place of worship for all nations these things are a pattern also of the glorification of the saints.

These links with the narrative of the 'fall'

Demonstrate that those 'in Christ' are freed from the condemnation of the curse. Jesus later offers the reward of sharing in the tree of life at the resurrection (Revelation 2:7)

"I will raise him up at the last day" Christ leaves no doubt that the will of God is that all that believeth on him, should be given eternal life; hence we have this phrase repeated four times: V.39; 40: 41: 54 

Vs.41,51,62 are often quoted as proof by some of the pre-existence of Christ.  However, like all scripture, a single theme must be taken in relation to other scripture. 

Clearly, Jesus is comparing himself to the manna, the bread from heaven, which appeared miraculously to feed the Children of God (Exo 16:14,15; v. 58).  The similarity between the two is that they both had their origin in heaven (i.e. God produced them). 

The manna was produced on earth by the divine hand hence it did not come floating down from the great reaches of space.  Likewise, Jesus was produced on earth, by God's power, and did not literally come down from heaven. 

Notice in v.62 that Jesus calls himself son of man.  Being a flesh and blood human precluded His appearance in heaven (1John 4:12).  Only after He was raised from the dead and immortalized did He join His Father in heaven (Acts 1:9-11; Rom 6:9; 8:34).

V.54 We have just read in V.53 "Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you", but, now Christ goes one step further, as he says, whoever does so "hath eternal life".

6:27 ‘labour … perisheth’ quotes Isa 55:2 where the free food is offered. This is what Jesus has just done. In the narrative, though in a different place at a different time. So we see that the theme of feeding is built into the chapter even though the events took place at different locations.

6:10 The feeding of the 5,000 is recorded in all four gospel records Matt 14:19, Mark 6:39, Luke 9:16. As such it is the only miracle recorded in all four gospels.

 6:15 Notice how Jesus avoids the adulation when the people wanted ’to make him king’ he went into a mountain to pray – prayer was Jesus’ solution to stressful and difficult situations.

V.12  Jesus was clear that no food fragments should be left.  This miracle, of providing temporal food, mirrors the divine provision of manna in the wilderness.  There too, nothing was to be left over (Exo 16:17-19).  

In relating the wilderness experience to the people, Jesus gave them the spiritual understanding that the manna represented Him (vs.32-35). 

Jesus taught His disciples that bread signified His body (Matt 26:26). 

Paul explained that true believers are members of Jesus' body (Rom 12:5). 

Each member, therefore, is a piece of the loaf (bread = body of Jesus).  Each member is precious, should be respected, and never discarded (please see 1 Cor Ch. 12).  

6:7 Philip’s incredulous comment matches Moses – Num 11:21-22 – when God says He will provide meat for Israel in the wilderness.

6:51,58  ‘eat ... live forever’ quotes Gen 3:22. So we see that those who come to Jesus are, so to speak, return into Eden before the fall – that is they regain the fellowship that Adam and Eve had with God before they sinned.
