Notice that there are 12 princes of tribes, even though Levi is not in the list. The two sons of Joseph are taken as two tribes not one.

In the last verse of this chapter Moses was hugely privileged to hear God's voice
  speaking to him from between the cherubim Num 7:89. The man-made furniture
  now was God's throne. We are the temple of living God 2Cor 6:16, and in our New
  Testament era the Lord God will dwell in us.  Let's listen for God's voice.

7:3-6     Whilst God had specified everything to do with the tabernacle the princes considered the matter of transporting the ark and were moved to make an offering to God which He accepted  at the hand of Moses.  Their offering was a free will offering – they saw a need and met it without having been told to do so. We should always be on the look out for situations where we can help before we are asked.

7:6-9 Whilst the wagons were a free will offering they could not be used in ways which violated what God had said, therefore the sons of Kohath had no wagons. Their job was to carry the furniture. This was a specific command from God. In the same way we need to realise that whilst we are free to give to God we must give according to His will not our own.

7:12   Judah offered first and was to lead the camp in their journeys.

v.9 From a human perspective, one can understand why Korah envied Moses and Aaron  (Num 16:3) : the Kohathites had to wait whilst the priests covered the items of furniture (Num 4:15, 19-20) and were not given transport on which to carry them, having to bear them on their shoulders. Yet God provided them with a work of service which was very important as Moses reminds them (Num 16:8-9). Are we ever envious of brethren and sisters who seem to be able to take on the more glamorous duties. Yet God has called us all and brought us all near, providing us with all we need to serve him in the way that he has chosen for us.

7:89 Even though Moses was by now anointed as high priest it was Moses who was the first man who heard the voice of God from between the Cherubims.

4:26  The paths that we should ‘ponder’ will cause us to make ‘straight paths’ - Heb 12:13 - that is we will walk correctly before God.

4:12 The wise man is not saying that wisdom will make one a capable athlete. The running is in the service of God in contrast to the feet that ‘run to shed blood’ – Prov 1:16

V.3 The word "beloved" is in italics, which indicates that it is not in the original, it has been put there to help us appreciate and understand the word "only". The Hebrew word is YACHIYD (3173) which we understand means beloved as well as only. God said to Abraham "Take now thy son, thine "only" Issac, whom thou lovest" (Gen 22:2) Isaac was a type of Christ, who was the "only" begotten Son of God (1John 4:9). Luke also records for us at the time of Christ's baptism "Thou art my beloved Son" (Luke 3:22) 

4:2 In saying he was "his father’s son’ the writer is appealing to the basis of his instruction. If we are truly ‘sons of God’ then the instruction we give will be true and right. It behoves us to show the Father in the way we instruct others.

The Hebrew word for wisdom is chokmah. In Hebrew today, a smart person (clever fellow) is called a chokam. It is also used derisively about somebody who thinks he is smart but is not. Oh, he’s such a chokam!

4:18 The ‘shining light ...’ is quoted – 2Pet 1:19 – when speaking of the value of ‘prophecy’ – actually Peter is speaking about all Scripture. So Peter’s use of this passage is consistent with the message of the wise man of the Proverbs.

4:10The promise of many years being given to the son who listens to the instruction of the father echoes Exo 20:12

V.13 The word "merciful" used here is an interesting study. The Greek word is HILASKOMAI (2433). The only other time it is used is in Heb 2:17 where it is translated "make reconciliation". The Greek meaning of the word is to make propitiation. With this in mind it assists in the understanding and appreciation of the next verse. The Publican was justified or made right. 

18:22  The call to follow Jesus has already been made to the disciples – Luke 9:23. We se, later in this chapter, that Bartimaeus did follow Jesus – Luke 18:43

18:8 We should realise that the ‘faith’ that the lord wonders will be manifest is a belief that God will actually hear and answer prayers. The context of the previous verses demonstrates this. We cannot form a judgment abut what the verse means without reference to it’s context.

18:9   This parable to those who ‘trusted in themselves’ – following hard on the comment of Jesus in the previous verses – must indicate that those who do not cry to God regularly actually trust in themselves.

18:15-17 We are so familiar with the way that Jesus speaks of receiving the kingdom as ‘a little child’ that we may miss the force of the point. Whilst children are self willed and rebellious they have the wonderful characteristic that they are teachable. They respond to teaching with enthusiasm and absorb new things like a sponge absorbs water. Are we so willing to learn the tings of God?

Luke seems to compare and contrast the rich ruler in Luke 18 with Zacchaeus in Luke 19. For example, we are told specifically they were both rich and in positions of authority - one a ruler, the other chief among the publicans. However, Zacchaeus volunteers to give up his money, whereas the ruler does not. Zacchaeus is joyful whereas the ruler is very sorrowful. Zacchaeus shows what is required to be an heir (son of Abraham) whereas the ruler does not.  

18:22,42 Notice the contrast between the ruler and Bartimaeus. The man who did not follow was amongst those who thought that they could see. Bartimaeus obviously couldn’t see. In reality the ruler couldn’t see and Jesus was curing his blindness as he did Bartimaeus. Bartimaeus was cured. The ruler was not so couldn’t follow – he still couldn’t see.
