2 Samuel 20:1-3

1There happened to be there a worthless and wicked man named Sheba the son of Bichri, a Benjamite. He blew a trumpet [to call Israel to revolt] and said, “We have no portion in David And no inheritance in the son of Jesse, Every man to his tents, O Israel!”

2So all the men of Israel deserted David and followed Sheba the son of Bichri; but the men of Judah stayed faithfully with their king, from the Jordan to Jerusalem.

3Then David came to his house (palace) at Jerusalem, and the king took the ten women, his concubines whom he had left to take care of the house, and placed them under guard and provided for them, but did not go in to them. So they were confined, and lived as widows until the day of their death.
