1CH 12:19

19 So David welcomed those men, and he appointed them to be leaders of his soldiers. Some men from the tribe of Manasseh also joined David when he went with the soldiers of Philistia to fight against Saul’s [army]. But David and his men did not really help the army of Philistia. After the leaders of Philistia talked [about David and his soldiers], they sent David away. They said, “If David joins his master Saul again, we will all be killed {his army will kill all of us}!”
