2 Samuel 20:5 KJV

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 ward, and fed them, but went not in unto them. So they were shut up unto the day of their death, living in widowhood.

4Then said the king to Amasa, Assemble me the men of Judah within three days, and be thou here present.

5So Amasa went to assemble the men of Judah: but he tarried longer than the set time which he had appointed him.

6And David said to Abishai, Now shall Sheba the son of Bichri do us more harm than did Absalom: take thou thy lord’s servants, and pursue after him, lest he get him fenced cities, and escape us.

7And there went out after him Joab’s men, and the Cherethites, and the Pelethites, and all the mighty men: and they went out of Jerusalem, to pursue after Sheba the son of Bichri.
