Maybe Psalm 35 was written out of these events. Notice these links.

There's lessons abundant in these stories of old. I am sure that the Lord's inspiration of these holy men of God made it possible for us to see ourselves in the character studies, and to learn lessons for our lives. David and Saul had talked peaceably, but David was wise enough not to go home together with him
(1Sam 24:17-22). You just can't trust some people.

24:7     Such was David’s position with his men hat a word from him and they obeyed. This is not the only time we find such obedience to david by his men.  We should be alert to the other examples in his life. Are we so obedient to the greater son of David?

V.3-5 - David spared Saul's life but no doubt this was a reminder not lost on Saul that the kingdom of Israel would be torn from him 1Sam 15:27-28.

V.12; 1Sam 25:33 - vengeance is mine saith the Lord Rom 12:19.

24:2      3,000 men to try to catch David! One wonders how Saul managed to find so many who wanted David dad. Or maybe they went with Saul but their heart was not in the matter – hence David was not caught.

David was thinking spiritually and not carnally when he spared Saul's life.  He respected Yahweh and the ones He chose, therefore, he did not give in to the actions of the flesh.  Hence, Yahweh could say about David that he was: ...a man after mine own heart... (Acts 13:22).

V.2 The KJV has the rocks of the wild goats, while the ESV employs a proper noun: Wildgoats' Rocks.  The reference to goats is in keeping with the place En-Gedi which means fountain of the kid.

V.4 The temptation for David to kill Saul must have been great.  David was afraid of nothing and no-one.  He had faced wild animals, and the giant of the Philistines without fear (1Sam 17:36).  He had Saul, the enemy who had been dogging him, in his grasp.  Killing him would solve all his problems. And yet, David deferred to Yahweh and did not exercise what seemed like a logical, human solution.

David is a great example for us of faith and constraint.  Divine solutions are to be preferred to human ones.  But we need faith not to give in to what seems plausible from a human perspective.  Trust in Yahweh is the key.  Take every problem to him faithfully in prayer and the right solution will follow (Prov 3:5,6; 16:3).

Vs.20-22 Through all the haze of his irrationality, Saul knew that David was Yahweh’s anointed.  With that admission, he wanted to make sure that his name and progeny would be protected.

1Sam 24:11,16 - David refers to King Saul as "my father" while Saul refers to David as "my son" which perhaps echos Christ being the son of God.

Jeremiah prophesied in Judah during the reign of Josiah and subsequent kings up until the Babylonian exile.  Therefore, his time of prophesying took place between 626 BC and sometime after 586 BC.

Vs.6,7,9 The humble disposition of Jeremiah is reminiscent of Moses (Exo 4:10-12).

Vs.11,12 There is an interesting play on Hebrew words.  In verse 11, almond = shakad which is related to hasten (KJV) = shakad in verse 12.  Actually, hasten is better translated watch as it is, subsequently, in Jer 31:28; 44:27; 51:12.  The almond blossoms early in spring and so the word that Yahweh gave Jeremiah would be broadcast early.  Yahweh would watch (be alert) to bring His Word to fruition.  The budding almond signified that Aaron was chosen as priest (Num 17:8).  Perhaps, in like manner, the almond signified Jeremiah as a chosen prophet (v.5).

1:14  The ‘seething pot’ that was to come out of the North was the Babylonian invasion.

V.5 Yahweh is without beginning and without end (Psa 90:2).  He knows all things that will occur before they happen.  That is the reason He can express His foreknowledge of Jeremiah. 

There are other examples, in the Bible, concerning His expressed foreknowledge of people.  These include the Lord Jesus Christ (John 17:24; 1Pet 1:20), and His true believers (Eph 1:4). 

These passages do not suggest that either Jeremiah or the followers of Christ pre-existed.  And yet, many people ascribe the same sort of passages, referring to Christ, as proving His pre-existence.  This, of course, is an attempt to give credence to the false doctrine of the Trinity.  

1:11,13 Jeremiah was shown two visions. The doubling of the vision guaranteed the things that God was saying – Gen 41:32

1:5 Whilst we might have difficulty understanding God’s foreknowledge we must accept that He had selected Jeremiah before his birth. This is the wonderful position the children of God are. Rather than trying to rationalise it we should simply accept it knowing that God’s thoughts are different from ours – Isa 55:8

1 As we start to read Jeremiah we doubtless are aware that the prophecy of Jeremiah is not in chronological order. Rather than try to re-organise the chapters maybe we should try to understand, from the way the book is constructed, what the purpose of the order is.

V.1 Anathoth was a city given to the priests, the sons of Aaron (Josh 21:18).

V.6 Jeremiah felt inadequate to carry out Yahweh’s commission.  This is reminiscent of Solomon’s feeling as he assumed the throne (1Kin 3:7).  But, Yahweh gives the required wisdom to His servants, as he did to Solomon (1Kin 4:29). Likewise, Yahweh gave Jeremiah the wisdom he needed (v.9).

And so, we should not be prevented from expanding our spiritual horizons because we feel inadequate. If we approach all things in faith and prayer, Yahweh will add the necessary wisdom (James 1:5).

V.13 a seething pot (KJV); boiling pot (ESV) indicates the fury of Yahweh which can be expressed in the turbulence of war as He sends nations to do His bidding. In this case, he used Babylon to punish Judah and Jerusalem.  For another example of this figurative expression of Yahweh’s anger, see Job 41:20.

V.19 The servant of Yahweh must expect that the Truth will not be accepted.  People do not want to hear bad things.  They did not in Jeremiah’s day, and they do not today. Nevertheless, we must be bold and speak the Truth, like Jeremiah did, even if it means ridicule, or worse. Jeremiah was ill-treated, but he will be in the Kingdom.  What about us?

The context of Jeremiah

God had turned over Israel (Samaria) to the Assyrians. They had laid the land waste and then resettled it. But Jerusalem had been spared. The time of Hezekiah was a time of prosperity and return to the worship of the true God. But Hezekiah only had 15 years. During this time Manasseh was born and became the most evil King in Judah's history. He immediatly set about to undo the good Hezekiah had done (2Kin 21:3). So great was his evil that he caused Judah to practice greater abominations than the nations God had driven out of the land, and that's saying something!

So God said He would overturn Judah with the same punishments as Samaria, wiping it clean like a bowl (2Kin 21:10-15). After Manasseh was his son Amon who followed his father's ways, and then Josiah reigned, his 8 year old son who again began to restore worship of the true God. This is where Jeremiah fits in. He began to speak out when Josiah was 21, and interestingly his message was not to be of hope but of judgement. To explain this we need to look at two important verses. 2Kin 23:25-26 explains how, though Josiah's heart was wholy to follow God, it wasn't enough to blot out the damage Manasseh had done. So in v27 of that chapter, a repeat of the promise "I will cast off this city Jerusalem".

God said to Jeremiah "I am ready to perform My word" (v12). He was to bring upon them a repeat of the Assyrian invasion, this time with the Babylonians, and this time without hope (v14-16). And Jeremiah was there to read them the accusation.

1:19  As God had chosen Jeremiah He also assured him that he would take care of Him. This is true of those of us who are chosen. Our lives are not a haphazard series of events.

A further point to ponder:
v 36 seems very harsh, until we read it in context. Jesus has just stated that out of the abundance of the heart come our words and speech. If this is the case, then the idle words (or those that weren't pre-meditated) we utter will betray what is in our hearts. Our idle words, then, will be the vehicle by which our hearts are exposed at the judgement. It will be the heart that is being judged, rather than the words themselves. An example of this is in verse 24. Jesus "knew their thoughts" (v25) because of what they had said.

V.24 Jesus was accused by the Pharisees of performing miracles by Beelzebub.  In Hebrew Beelzebub is Baal Zvuv which literally means Master (or Lord) of the fly.  Its derogatory connotation is Lord of Dung (the place where flies gather most). 

Vs.31,32 Thus, the Pharisees, instead of welcoming the miraculous power of God, cast aspersions on the Holy Spirit.  The Lord issued the sternest of warnings about this. 

We should be careful also to respect the Word, which is an expression of the Spirit, lest we be judged unworthy.  Disobeying the Word, by conducting ourselves inappropriately, is equated with blasphemy (Titus 2:1-5).

12:14 The Pharisees had already decided the answer to the question that they raised in 12:10 Their intention was not to learn truth. Rather it was to trap Jesus in his words and actions. We can be like this, having decided that someone is wrong we question them in a way which enable us to confirm our prejudice against that person.

12:41 Jesus is presented as ‘greater than Jonah’. There are a number of ways in which he was ‘greater than Jonah’. One is that he was willing to preach to sinners, Jonah preferred not to. Jonah knew that God was gracious – Jon 4:2 and so did not want to preach to Nineveh. Jesus, knowing the God was gracious, preached to sinners.

A MIRACULOUS SIGN

"Then some of the Pharisees and teachers of the law said to him, 'Teacher, we want to see a miraculous sign from you.' He answered, 'A wicked and adulterous generation asks for a miraculous sign! But none will be given it except the sign of the prophet Jonah. For as Jonah was three days and three nights in the belly of a huge fish, so the Son of Man will be three days and three nights in the heart of the earth.'"(Matt 12:38-40)

It is interesting that right through his ministry, Jesus gave sign after sign that he was a man of God, and that he was no less than the son of God. Many people saw those signs and believed. The ones that should have seen them first were the Pharisees and the teachers of the law. They were the ones with their noses in the Bible, who knew by heart all the prophesies of the Messiah, and yet they just couldn't see who he was. God had given them all the signs that they needed, but they refused to believe.

Even today people ask for signs. Just like it was in the days of the Pharisees and teachers of the law, there are signs all over the place that God exists and is alive and active. There may be times where God has to give us a special sign, but for the most part we have all the evidence we need right in front of us. Lets not close our eyes to the signs in the word of God, in the world around us, and in our individual lives, but open them up to see the evidence of God in the ways he has chosen to reveal himself to us.

12:10 Earlier in the day they had confronted Jesus about sabbath breaking with the matter of the corn. Now in the synagogue on the same day they try again to discredit Jesus.

V.7 See Hos 6:6; Mic 6:6-8

V.14 The Pharisees were furious because their pride had been pricked (Luke 6:11).

Vs.18-21 See Isa 42:1-4.

V.30 One is either 100% with Jesus, or 100% against Him.  There are no half-measures, although a lot of people do try to mix and match. The choice is as clear today as it was in Joshua’s day (Josh 24:15). There are going to be many people at the judgment who are going to be hugely shocked and disappointed (Matt 7:22,23).

Vs.36,37 These verses should be very sobering, as it is easy to speak inappropriately.

12:22 Jesus’ miracles were not simply acts of kindness. They had deeper spiritual significance also. The man who was blind and dumb represented Israel’s leaders. Jesus taught that they were ‘blind’ Matt 15:14. Because they were ‘blind’ to the teaching of the law they were ‘dumb’ also – that is they were unable to teach the law.
