In between the letter of James and the first letter of Peter we read two psalms and one chapter of Ezekiel.
Psalm 135 is a Psalm of praise and thanksgiving to the uniqueness and superiority of the LORD and His name and all that He has done! Compare that to the worthless idols!
Psalm 136 is called the Great Hallel (or Great Psalm of Praise). Each one of its 26 verses repeats the phrase, “His mercy endureth forever.” It was sung responsively by the Levites and the assembly of people at both Solomon’s and Zerubbabel’s temple dedication and is now sometimes sung or recited at Passover.
Ezekiel 33. The prophet takes the role of the watchman and gives a message about God’s Judgment and it’s fairness, tells of the f all of Jerusalem and the cause of Judah’s ruin being they are hearing but not doing, still continuing their sinful acts.
