1st Samuel 23:6

3 And David`s men said unto him, Behold, we are afraid here in Judah: how much more then if we go to Keilah against the armies of the Philistines?

4 Then David inquired of Jehovah yet again. And Jehovah answered him, and said, Arise, go down to Keilah; for I will deliver the Philistines into thy hand.

5 And David and his men went to Keilah, and fought with the Philistines, and brought away their cattle, and slew them with a great slaughter. So David save the inhabitants of Keilah.

6 And it came to pass, when Abiathar the son of Ahimelech fled to David to Keilah, that he came down with an ephod in his hand.

7 And it was told Saul that David was come to Keilah. And Saul said, God hath delivered him into my hand; for he is shut in, by entering into a town that hath gates and bars.

8 And Saul summoned all the people to war, to go down to Keilah, to besiege David and his men.

9 And David knew that Saul was devising mischief against him; and he said to Abiathar the priest, Bring hither the ephod.
