2 Samuel 20:6-8

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 fortified cities and escape our sight.

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.

8When they were at the great stone which is in Gibeon, Amasa came before them. And Joab was girded with his coat, his dress, and upon it was the girdle of the sword which was fastened on his loins in its sheath; and as he went forth it fell out.
