II Samuel 20:8

8 While they were at the great rock in Gibeon, Amasa came to meet them. Joab was wearing his military tunic, and strapped over it at his waist was a belt with a dagger in its sheath. As he stepped forward, it dropped out of its sheath.

8 Quando chegaram à grande rocha em Gibeom, Amasa foi ao encontro deles. Joabe vestia seu traje militar e levava um punhal preso ao cinto. Quando deu um passo à frente para saudar Amasa, tirou o punhal da bainha.
