The son of Maoch and the king of Gath, to whom David twice fled during the time that he was persecuted by Saul (1 Sam. 21:10-15; 27:1-12; 28:1, 2; 29:1-11). He is probably the Achish who was king of Gath at the beginning of Solomon's reign: for the latter was the son of Maachah, a name which is radically identical with Maoch the father of the Achish already known. The reign of about fifty years required by this assumption is not extraordinary (cp. among many others the reigns of Uzziah and Manasseh). Achish survived his contemporary, David, at least three years (1 Kin. 2:39). In the title of Ps. 34. he is called Abimelech, which appears to have been an official designation of the Philistine kings as Pharaoh was a title of the Egyptian monarchs.
