Lachish (lâ'kish), invincible. A city of the Amorites, lying south of Jerusalem, and toward the border of Simeon. Joshua 10:1-43; Joshua 3:1-17. It was one of the Canaanitish cities which was subdued by Joshua and included in Judah; fortified by Jeroboam. 2 Chronicles 11:9. King Amaziah was killed there. 2 Kings 14:19. Lachish was besieged by Sennacherib and perhaps taken. 2 Kings 18:13-14; Isaiah 36:1-2. The siege is considered by some to be depicted on the slabs found in one of the chambers of the palace at Kouyunjik. Lachish has lately (1892) been identified with Tel-el-Hesy on the Mediterranean Sea, where remarkable tablets, records, and letters of the king of Lachish have been found, written before the exodus.
