2 Samuel 20:5

So all the men of Israel went up from following David, and followed Sheba the son of Bichri; but the men of Judah joined with their king, from the Jordan even to Jerusalem.

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 provided them with sustenance, but didn’t go in to them. So they were shut up to the day of their death, living in widowhood.

Then the king said to Amasa, “Call me the men of Judah together within three days, and be here present.”

David said to Abishai, “Now Sheba the son of Bichri will do us more harm than Absalom did. Take your lord’s servants and pursue after him, lest he get himself fortified cities, and escape out of our sight.”

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

When they were at the great stone which is in Gibeon, Amasa came to meet them. Joab was clothed in his apparel of war that he had put on, and on it was a sash with a sword fastened on his waist in its sheath; and as he went along it fell out.
