Yes, I think the most amazing as a lesson of redemption were the “Sons of Korah” who wrote some Psalms. Korah was a cousin of Moses who rebelled against Moses, Aaron and God but his sons reformed and repented before being swallowed up by the earth and ended up being quoted in the Bible.
The sons of Korah are credited with writing eleven different Psalms: Psalms 42, 44, 45, 46, 47, 48, 49, 84, 85, 87, 88.
Yes.
Jewish tradition records 10 more authors of at least one Psalm: Adam, Melchizedek, Abraham, Moses, Heiman, Yedutun, Asaph, and the three sons of Korach.
