2 Samuel 20:3-5

3Then David came to his house (palace) at Jerusalem, and the king took the ten women, his concubines whom he had left to take care of the house, and placed them under guard and provided for them, but did not go in to them. So they were confined, and lived as widows until the day of their death.

4Now the king said to Amasa [the commander of his army], “Summon the [fighting] men of Judah to me within three days, and be present here yourself.”

5So Amasa went to summon [the fighting men of] Judah, but he delayed longer than the time which David had set for him.
