2 Samuel 20:18

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

So every man of Israel went up from after David, and followed Sheba the son of Bichri: but the men of Judah clave unto their king, from Jordan even to Jerusalem.

And David came to his house at Jerusalem; and 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 went not in unto them. So they were shut up unto the day of their death, living in widowhood.

Then said the king to Amasa, Assemble me the men of Judah within three days, and be thou here present.
