1 Chronicles 12:17

12:17 David went out to meet them and said, “If you come to me in peace and want to help me, then I will make an alliance with you. But if you come to betray me to my enemies when I have not harmed you, may the God of our ancestors take notice and judge!”

1 Chronicles 12:19

12:19 Some men from Manasseh joined David when he went with the Philistines to fight against Saul. (But in the end they did not help the Philistines because, after taking counsel, the Philistine lords sent David away, saying: “It would be disastrous for us if he deserts to his master Saul.”)
