Between Second Thessalonians and First Timothy we read one chapter of Proverbs and two chapters if Jeremiah.
Proverbs 15, Proverbs of Solomon. Solomon speaks of the value of following the LORD and the pursuit of righteousness and virtue as opposed to folly, pride and wickedness, which God hates.
Jeremiah 3. Israel is shamelessly unfaithful, yet God is merciful and calls Israel to repent ans return.
Jeremiah 4. God makes one final call for Israel to repent, but, and this is the prophecy, there will be an imminent invasion and the nation is doomed.
