Albert Barnes Commentary 1 Samuel 23:12

"Then said David, Will the men of Keilah deliver up to me and my men into the hand of Saul? And Jehovah said, They will deliver thee up." — 1 Samuel 23:12 (ASV)

The conduct of the men of Keilah would be like that of the men of Judah toward Samson, their deliverer (Judges 15:10–13).
