1 Samuel 25:10-17

And Nabal answered David’s servants, and said, Who is David? and who is the son of Jesse? there are 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 of whom I know not whence they are? So David’s young men turned on their way, and went back, and came and told him according to all these words. 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 baggage. But one of the young men told Abigail, Nabal’s wife, saying, Behold, David sent messengers out of the wilderness to salute our master; and he railed at them. But the men were very good unto us, and we were not hurt, neither missed we anything, as long as we went with them, when we were in the fields: they were a wall unto us both by night and by day, all the while we were with them keeping the sheep. Now therefore know and consider what thou wilt do; for evil is determined against our master, and against all his house: for he is such a worthless fellow, that one cannot speak to him.
