תּלמוד אויף בראשית 20:17

MISHNAH: Even though he did pay, he will not be forgiven⁷⁸The person who injures another cannot obtain mercy in Heaven unless he first has asked forgiveness on earth. unless he asks for forgiveness, as it is said: “Now return the man’s wife since he is a prophet⁷⁹Gen. 20:7. The reference as usual is to the part of the verse which is not quoted: “Let him pray for you that you will live.” This implies that Abraham first had to forgive Avimelekh before the latter obtained Heavenly mercy..” From where that the person asked to forgive shall not be cruel? It is said⁸⁰Gen. 20:17.: “Abraham prayed to the Omnipotent, etc.”

[Rava] said to [Rabbah bar Mari]: You derive it from there and I derive it from here. “And Abraham prayed to God [and God healed Abimelekh and his wife and his maid-servants and they gave birth]” (Genesis 20:17). And it is written after it: “And the Lord remembered Sarah, as he had spoken…” (Genesis 21:1). As Abraham had spoken about Abimelekh.
