SHESHACH.—A cryptic name of Babel, found in the received text of Jer_25:26; Jer_51:41. It is formed by the method called Atbash, that is a substitution of lau for aleph, shin for beth, and so on. The word is, however, no part of the original text of Jeremiah, being a conceit of later editors. In both passages it is lacking in LXX. [Note: Septuagint.] Cf. Leb-kamai.
