Achish in the Bible

(King of the Philistines, also called ABIMELECH) David escapes to

1 Samuel 21:10-15 And David arose, and fled that day for fear of Saul, and went to Achish the king of Gath. 11 And the servants of Achish said unto him, Is not this David the king of the land? did they not sing one to another of him in dances, saying, Saul hath slain his thousands, and David his ten thousands? 12 And David laid up these words in his heart, and was sore afraid of Achish the king of Gath. 13 And he changed his behaviour before them, and feigned himself mad in their hands, and scrabbled on the doors of the gate, and let his spittle fall down upon his beard. ...
1 Samuel 27 And David said in his heart, I shall now perish one day by the hand of Saul: there is nothing better for me than that I should speedily escape into the land of the Philistines; and Saul shall despair of me, to seek me any more in any coast of Israel: so shall I escape out of his hand. 2 And David arose, and he passed over with the six hundred men that were with him unto Achish, the son of Maoch, king of Gath. 3 And David dwelt with Achish at Gath, he and his men, every man with his household, even David with his two wives, Ahinoam the Jezreelitess, and Abigail the Carmelitess, Nabal's wife. 4 And it was told Saul that David was fled to Gath: and he sought no more again for him. ...
1 Samuel 28:1-2 And it came to pass in those days, that the Philistines gathered their armies together for warfare, to fight with Israel. And Achish said unto David, Know thou assuredly, that thou shalt go out with me to battle, thou and thy men. 2 And David said to Achish, Surely thou shalt know what thy servant can do. And Achish said to David, Therefore will I make thee keeper of mine head for ever.
1 Samuel 29 Now the Philistines gathered together all their armies to Aphek: and the Israelites pitched by a fountain which is in Jezreel. 2 And the lords of the Philistines passed on by hundreds, and by thousands: but David and his men passed on in the rereward with Achish. 3 Then said the princes of the Philistines, What do these Hebrews here? And Achish said unto the princes of the Philistines, Is not this David, the servant of Saul the king of Israel, which hath been with me these days, or these years, and I have found no fault in him since he fell unto me unto this day? 4 And the princes of the Philistines were wroth with him; and the princes of the Philistines said unto him, Make this fellow return, that he may go again to his place which thou hast appointed him, and let him not go down with us to battle, lest in the battle he be an adversary to us: for wherewith should he reconcile himself unto his master? should it not be with the heads of these men? ...
