1 Samuel 25:10-13

25:10 But Nabal responded to David’s servants, “Who is David, and who is this son of Jesse? This is a time when many servants are breaking away from their masters! 25:11 Should I take my bread and my water and my meat that I have slaughtered for my shearers and give them to these men? I don’t even know where they came from!”

25:12 So David’s servants went on their way. When they had returned, they came and told David all these things. 25:13 Then David instructed his men, “Each of you strap on your sword!” So each one strapped on his sword, and David also strapped on his sword. About four hundred men followed David up, while two hundred stayed behind with the equipment.
