Achish

angry, perhaps only a general title of royalty applicable to the
Philistine kings. (1.) The king with whom David sought refuge
when he fled from Saul (1 Sam. 21:10-15). He is called Abimelech
in the superscription of Ps. 34. It was probably this same king
to whom David a second time repaired at the head of a band of
600 warriors, and who assigned him Ziklag, whence he carried on
war against the surrounding tribes (1 Sam. 27:5-12). Achish had
great confidence in the valour and fidelity of David (1 Sam.
28:1,2), but at the instigation of his courtiers did not permit
him to go up to battle along with the Philistine hosts (1 Sam.
29:2-11). David remained with Achish a year and four months.
(2.) Another king of Gath, probably grandson of the foregoing,
to whom the two servants of Shimei fled. This led Shimei to go
to Gath in pursuit of them, and the consequence was that Solomon
put him to death (1 Kings 2:39-46).
