In between first and second Corinthians we read two Psalms and the first two chapters of Ezra.
Psalm 49, of the Sons of Korah. This psalm is more of a teaching Psalm and gives instruction on how to live and hope of salvation “But God will redeem my soul from the power of the grave, For He shall receive me”
Psalm 50, of Asaph. God says “for every animal of the forest is mine,
and the cattle on a thousand hills.” and “Sacrifice thank offerings to God,
fulfill your vows to the Most High,
and call on me in the day of trouble;
I will deliver you, and you will honor me.”
Ezra 1 begins with the end of the Babylonian captivity and Cyrus decree to rebuild the Temple.
Ezra 2 lists the captives who returned to Jerusalem.
