1 Samuel 25:8-14
English Standard Version
9When David 's young men came, they said all this to Nabal in the name of David, and then they waited.
10And Nabal answered David 's servants, "Who is David? Who is the son of Jesse? There are many servants these days who are breaking away from their masters.
11Shall I take my bread and my water and my meat that I have killed for my shearers and give it to men who come from I do not know where?"
12So David 's young men turned away and came back and told him all this.
13And David said to his men, "Every man strap on his sword!" And every man of them strapped on his sword. David also strapped on his sword. And about four hundred men went up after David, while two hundred remained with the baggage.
