1 Chronicles 12:24 (KJV)

And there fell some of Manasseh 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 to his master Saul to the jeopardy of our heads.

As he went to Ziklag, there fell to him of Manasseh, Adnah, and Jozabad, and Jediael, and Michael, and Jozabad, and Elihu, and Zilthai, captains of the thousands that were of Manasseh.

And they helped David against the band of the rovers: for they were all mighty men of valour, and were captains in the host.

For at that time day by day there came to David to help him, until it was a great host, like the host of God.

And these are the numbers of the bands that were ready armed to the war, and came to David to Hebron, to turn the kingdom of Saul to him, according to the word of the LORD.

Of the children of Simeon, mighty men of valour for the war, seven thousand and one hundred.

Of the children of Levi four thousand and six hundred.

And Jehoiada was the leader of the Aaronites, and with him were three thousand and seven hundred;

And Zadok, a young man mighty of valour, and of his father's house twenty and two captains.

And of the children of Benjamin, the kindred of Saul, three thousand: for hitherto the greatest part of them had kept the ward of the house of Saul.
