1 Chronicles 12:19-22

19Of Manasseh also there fell away some to David, when he came with the Philistines against Saul to battle: but they helped them not; for the lords of the Philistines upon advisement sent him away, saying, He will fall away to his master Saul to the jeopardy of our heads. 20As he went to Ziklag, there fell to him of Manasseh, Adnah, and Jozabad, and Jediael, and Michael, and Jozabad, and Elihu, and Zillethai, captains of thousands that were of Manasseh. 21And they helped David against the band of rovers: for they were all mighty men of valor, and were captains in the host. 22For from day to day men came to David to help him, until there was a great host, like the host of God.
