Pensée juive sur Isaïe 59:20

When the penitent combines these four components along with their conditions, which we will clarify [next chapter], the Creator will forgive the sinner his iniquity, and overlook his transgression. If it is a sin of the type which it is written: "he will not hold him guiltless" (Shmos 20:7), such as a false oath or adultery, the Creator will reduce his punishment in this worldand show him grace in the Olam Haba (afterlife), and he will be included in the group of tzadikim (righteous), as written "And a redeemer shall come to Zion, and to those who repent of transgression in Jacob, says the L-ord" (Yeshaya 59:20), and "If you return, O Israel, says the L-ord, to Me you shall return" (Yirmiya 4:1), and "thus says the L-rd, If you return, then will I bring you again, and you shall stand before Me" (Yirmiya 15:19).

Chapter forty-four states that the tradition which we now have of the words of the prophets is true without any doubt and there is no possibility of there being any falsehood therein. It is pointed out also that this is a sign of the covenant between us and God pointing to the redemption, and the verses Isaiah 59, 20–21 are explained in this sense.
