1 Samuel 27:12

And they said to them, “May Yahweh look upon you and judge, for you have made us a foul smell in Pharaoh’s sight and in the sight of his servants, to put a sword in their hand to kill us.”

Then Achish called David and said to him, “As Yahweh lives, you have been upright, and your going out and your coming in with me in the camp are pleasing in my sight; for I have not found evil in you from the day of your coming to me to this day. Nevertheless, you are not pleasing in the sight of the lords.

And David said to Achish, “But what have I done? And what have you found in your servant from the day when I came before you to this day, that I may not go and fight against the enemies of my lord the king?”

Then the sons of Ammon saw that they had become odious to David. So the sons of Ammon sent and hired the Arameans of Beth-rehob and the Arameans of Zobah, 20,000 foot soldiers, and the king of Maacah with 1,000 men, and the men of Tob with 12,000 men.
