The early sages (the Tanaaim) listed the evil kings who had no portion in the World to Come: Yiravam the son of Nevat, Achav, and Menasseh. One sage, Rava, asked another, Rabbah the son of Meri: Why did the Tanaaim not include King Yehoiakim as a king who has no portion in the World to Come? The Scriptures note that he was evil — “Now the rest of the acts of Yehoiakim, and his abominations which he did, and that which was found on him, behold, they [are] written in the book of the kings of Israel and Judea” (II Chronicles 36:8). The sages interpreted the words that which was found on him to mean that there was an idolatrous tattoo on his sexual organ; some of the sages interpreted the words to mean that there was a tattoo with the name of G-d on his penis, intended to belittle the G-d of Israel. This shows that Yehoiakim was very evil indeed. So why was he not listed along with the other evil kings of Israel and of Judea? The sage’s answer: I have not heard nor do I know of an answer to this.
