2 Samuel 20:3-5

3And 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 custody, and fed them, but went not in to them. So they were shut up to the day of their death, living in widowhood.123

4Then said the king to Amasa, Assemble to me the men of Judah within three days, and be thou here present.4 5So Amasa went to assemble the men of Judah: but he tarried longer than the set time which he had appointed him.5
