2 Samuel 20:3-5

3Now 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 seclusion and supported them, but did not go in to them. So they were shut up to the day of their death, living in widowhood.

4And the king said to Amasa, “Assemble the men of Judah for me within three days, and be present here yourself.”

5So Amasa went to assemble the men of Judah. But he delayed longer than the set time which David had appointed him.
