In between First and Second Timothy we read three Psalms and one chapter of Jeremiah.
Psalm 108, a Psalm, a song of David. Here David repeats parts from Psalm 57 and Psalm 60 and uses it to ask for God’s help in his further conquests as he subdues nations around him.
Psalm 109, of David. Leaving vengeance to God, David prays for the full measure of God’s vengeance to be poured out on his wicked enemies. He is “poor and needy” and vengeance is God’s business.
Psalm 110, of David. Two quotes stand out from this Psalm: “The Lord said unto my Lord, Sit thou at my right hand, until I make thine enemies thy footstool.“, and “The Lord hath sworn, and will not repent, Thou art a priest for ever after the order of Melchizedek.” Who is David talking about? Hint: The book of Hebrews gives the answer.
Jeremiah 20. The chief priest Pashhur hears Jeremiah prophesy bad outcomes, so he punishes Jeremiah, which leads to the word of God to Pashhur. Jeremias gives yer another complaint to God, this time even to the point of complaining he was born.
