2 Samuel 20:2-4

New Revised Standard Version, Anglicised

² So all the people of Israel withdrew from David and followed Sheba son of Bichri; but the people of Judah followed their king steadfastly from the Jordan to Jerusalem.

³ David came to his house at Jerusalem; and the king took the ten concubines whom he had left to look after the house, and put them in a house under guard, and provided for them, but did not go in to them. So they were shut up until the day of their death, living as if in widowhood.

⁴ Then the king said to Amasa, ‘Call the men of Judah together to me within three days, and be here yourself.’
