2 Samuel 20:1-3

1 And a man of Belial happened to be there, whose name [was] Sheba, the son of Bichri, a man of Jemini, and he blew the shofar, saying, We have no part in David, neither have we inheritance in the son of Jesse. Every man to his tents, O Israel.

2 So all the men of Israel went up from after David [and] followed Sheba, the son of Bichri; but the men of Judah cleaved unto their king from the Jordan even to Jerusalem.

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