2 Samuel 20:2-4

2 So all the Israelites left David and followed Sheba son of Bicri. But the men of Judah stayed with their king all the way from the Jordan River to Jerusalem.

3 David came to his palace in Jerusalem. Earlier he had left there ten of his slave women who gave birth to his children. He had left them there to take care of the palace. Now he put them in a house where they would be guarded. They were kept there for the rest of their lives. David gave them food, but he did not have physical relations with them. They lived like widows until they died.

4 The king said to Amasa, “Tell the men of Judah to meet with me in three days. And you must also be here.”
