2 Samuel 20:6-8

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

7 Then Joab's men went out after him, 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.

8 When they [were] at the great stone which [is] in Gibeon, Amasa came out and met them. And Joab's garment that he had put on was girded unto him and upon it a girdle [with] a sword fastened upon his loins in its sheath, and as he went forth, it fell out.
