Midrasz do Królów II 21:3

Manasseh, means he has forgotten the Lord. According to others it means that he made Israel forget their Heavenly Father. And whence do we know that he has no share in the world to come? From the following passage (II Kings 21, 3) And he built up again the high places which Hezekiah hath destroyed and he reared up altars for Baal and made a grove as Achab the king of Israel hath done. As Achab has no share in the world to come, so is the case with Manasseh. R. Juda said: "Manasseh has a share, etc." R. Jochanan said: "Both infer their theory from one and the same passage, for it is said (Jer. 15, 4) And I will cause them to become a horror unto all the kingdoms of the earth on account of Manasseh the son of Hezekiah. According to one: Because Manasseh had repented and the other kings have not. And according to others: (Fol. 103) Because he himself had not repented." R. Jochanan said: "He who said that Manasseh has no share in the world to come laxes the hands of those who [desire to] repent, for a disciple taught before R. Jochanan: Manasseh repented thirty-three years, as it is wriitten (II Kings 21, 1-3) And he reigned five and fifty years in Jerusalem … and made an Asherah, as did Achab. How long did Achab rule? Twenty-two years; deduct the twenty-two from the fifty-five years which Manasseh reigned, there remains thirty-three years." R. Jochanan said in the name of R. Simon b. Jochai: "What is the meaning of the passage (II Chr. 33, 13) And he prayed unto Him, and he was entreated of him (vayechtar). It should have been vayethar, instead of vayechtar? Infer from this that the Lord made an opening for him in the Heaven to receive him; because of the [opposition] of the Divine Attribute of Justice."
