1 Samuel 25:9-13

And when David’s young men came, they spake to Nabal according to all those words in the name of David, and ceased.

And Nabal answered David’s servants, and said, Who is David? and who is the son of Jesse? there be many servants now a days that break away every man from his master.

Shall I then take my bread, and my water, and my flesh that I have killed for my shearers, and give it unto men, whom I know not whence they be?

So David’s young men turned their way, and went again, and came and told him all those sayings.

And David said unto his men, Gird ye on every man his sword. And they girded on every man his sword; and David also girded on his sword: and there went up after David about four hundred men; and two hundred abode by the stuff.
