Midrash su Ezechiele 33:12

(Ib. b) Our Rabbis were taught: Always shall a man consider himself as if his merits and his crimes are equally balanced; that if he fulfills a commandment then he will be happy, for that commandment will counterbalance the scale to the side of merits. If he commits an inquity then woe to him, for that crime will counterbalance the scale to the side of guilt, as it is said (Ecc. 9, 18) But one sinner causeth much to be lost, This means that one single crims which that man committed causes the loss of much goodness from him and from the entire world. R. Simon b. Jochai says: "Even a man who was perfectly righteous during his entire life and rebelled [against God] in the end will lose the credit of all his previous merits, as it is said (Ez. 33, 12) The righteousness of the righteous shall not deliver him on the day of his transgression; and on the contrary, even if one was grossly wicked during his entire life but repented in the end, none of his iniquities will be mentioned at Judgment, as it is said (Ib., ib., ib.) And as for the wickedness of the wicked he shall not stumble through it on the day that he returneth from his wickedness." Why should not such a man be considered equally divided, one-half of merits and one-half of iniquities? Said Resh Lakish: "This former refers to one who regrets his first [wicked] deeds."

“His palate is sweet and all of him is delightful. This is my beloved, and this is my companion, daughters of Jerusalem” (Song of Songs 5:16).
“His palate is sweet” – it is written: “For so said the Lord to the house of Israel: Seek Me and live” (Amos 5:4). Is there a palate that is greater and sweeter than that?⁸⁸Is there any statement sweeter than this statement by God? It is written: “As I live – the utterance of the Lord God – I do not desire the death of the wicked, [but that the wicked repent from his way and live]” (Ezekiel 33:11). Is there a palate that is greater and sweeter than that? “For I do not desire the death of the one who dies, the utterance of the Lord God; facilitate repentance and live” (Ezekiel 18:32). Is there a palate that is greater and sweeter than that? “If the wicked man turns away from his wickedness [that he did] and performs justice and righteousness, he will cause his soul to live” (Ezekiel 18:27). Is there a palate that is greater and sweeter than that?
Reish Lakish said: This is only if one has remorse for his previous actions. How so? Rabbi Shimon ben Yoḥai taught: If there was a person who was completely wicked all his days and ultimately he became completely righteous, in his regard the verse states: “The wickedness of the wicked person, he will not stumble over it on the day of his repentance from his wickedness…” (Ezekiel 33:12). Rabbi Yoḥanan said: Moreover, all the transgressions that he performed, the Holy One blessed be He tallies them for him as merits. That is what is written: “Myrrh, aloe, and cassia were on all your garments [bigdotekha]” (Psalms 45:9). All the betrayals [begidot] that you betrayed Me, they are like myrrh and aloe before Me.
It is taught: How old was Abraham when he recognized his Creator? Rabbi Ḥanina and Rabbi Yoḥanan both say: At the age of forty-eight Abraham recognized his Creator. Rabbi Shimon ben Lakish said: He was three years old, as it is stated: “Because [ekev] Abraham heeded My voice” (Genesis 26:5) – the numerical value of ekev.⁸⁹Ayin – 70, kof –100, bet – 2 = 172. He died at the age of one hundred and seventy-five and heeded God’s voice for one hundred and seventy-two of them. Thus, he recognized God at the age of three. Rabbi Levi said: When he was able to lift his heel [ikva] off the ground.
