Midrasch zu Jirmejahu 21:9

R. Juda said: "Exile atones for three things, as it is said (Jer. 21, 9) He that remaineth in this city shall die by the sword, or by the famine, or by the pestilence; but he that goeth out and runneth away to the Chaldeans that besiege you, shall remain alive, and his life shall be unto him as a booty." R. Jochanan, however, said: "Exile atones for every thing, for it is said (Ib. 22, 30) Thus hath said the Lord, write ye down this man as childless, as a man that shall not prosper in his days; for no man of his seeds shalt succeed to sit upon the throne of David, and to rule any more in Judah. And after he was exiled it is written (I Chr. 3, 17) And the sons of Yechanyah: Assir, Shealthiel his son. And there is a tradition that Assir and Shealthiel is the same person; he was called Assir, because his mother became pregnant when she was imprisoned; Shealthiel because he was planted by God not in the ordinary way of those that are planted [in prison]. In another way the name, Shealthiel, may be explained, concerning whom the Almighty asked an absolution upon the vow; who was planted in Babel. What was his real name — Nehemiah b. Cha'chalia.
