1 Samuel 29:2-4

New Century Version

² The Philistine kings were marching with their groups of a hundred and a thousand men. David and his men were marching behind Achish. ³ The Philistine commanders asked, “What are these Hebrews doing here?”

Achish told them, “This is David. He served Saul king of Israel, but he has been with me for over a year now. I have found nothing wrong in David since the time he left Saul.”

⁴ But the Philistine commanders were angry with Achish and said, “Send David back to the city you gave him. He cannot go with us into battle. If he does, we’ll have an enemy in our own camp. He could please his king by killing our own men.
