'Defected' in the Bible

Then he gathered together all of Judah, Benjamin, and people from Ephraim, Manasseh, and Simeon who were living among them, since many people had defected to him from Israel when they learned that the LORD his God was with him.

Nebuzaradan the captain of the guard carried into exile some of the poorest of the people, the rest of the people left in the city, the deserters who had defected to the king of Babylon, and the rest of the craftsmen.
