2 Samuel 20:3-5

3When David returned to his palace in Jerusalem, he took the ten concubines he had left to take care of the palace and put them in a house under guard. He provided for them but had no sexual relations with them. They were kept in confinement till the day of their death, living as widows.

4Then the king said to Amasa, “Summon the men of Judah to come to me within three days, and be here yourself.”

5But when Amasa went to summon Judah, he took longer than the time the king had set for him.
