2 Samuel 20:6-8

6 David said to Avishai, “Sheva the son of Bikhri is going to do us more harm than Avshalom. Take your lord’s servants and pursue him, so that he won’t take over fortified cities and escape us.”

7 With him went Yo’av’s men, the K’reti, the P’leti and all the experienced soldiers; they left Yerushalayim in pursuit of Sheva the son of Bikhri.

8 On arrival at the big rock in Giv‘on, ‘Amasa came to meet them. Yo’av was wearing his battle clothes, over which he had girded a belt with a sheathed sword; but as he came forward it fell out.
