Philistines: Kings of Achish

That day David fled from Saul and went to Achish king of Gath. …

So David set out with his six hundred men and went to Achish son of Maoch, the king of Gath. …

Now in those days the Philistines gathered their forces for warfare against Israel. So Achish said to David, “You must understand that you and your men are to go out to battle with me.”

David replied, “Then you will come to know what your servant can do.” “Very well,” said Achish. “I will make you my bodyguard for life.”

Now the Philistines brought all their forces together at Aphek, while Israel camped by the spring in Jezreel.
