In between Paul’s letter to Philemon and the letter to the Hebrews we read two Psalms and three chapters of Jeremiah.
Psalm 121, a Song of Accents. Psalms 120 to 134 were sung on the way to Jerusalem during the festivals.
Psalm 122, a Song of Accents. This one is of David.
Jeremiah 45. In 5 verses God gave assurance to Baruch to save his life, but disaster on the people.
Jeremiah 46. God proclaimed judgment on Egypt. Babylonia will strike Egypt but God will preserve Israel.
Jeremiah 47. And finally, there will be judgment on Philistia.
