2 Samuel 20:1-3

1And there happened to be there a man of Belial, whose name was Sheba, the son of Bichri, a Benjaminite; and he blew a trumpet, and said, We have no portion in David, neither have we inheritance in the son of Jesse: every man to his tents, Israel.

2Then all the men of Israel went up from after David, following Sheba the son of Bichri. But the men of Judah clave to their king, from the Jordan even to Jerusalem.

3And David came to his house at Jerusalem; and the king took the ten women, concubines, whom he had left to keep the house, and put them in a house of confinement and maintained them, but did not go in to them. So they were shut up unto the day of their death, living in widowhood.
