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 que está em Gibeom, Amasa veio ao encontro deles. Joabe estava vestindo seu traje de guerra e trazia um cinto com um punhal na bainha. Ao aproximar-se de Amasa, deixou cair a adaga.
