1 Samuel 25:10-17

10And 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.

11And shall I take my bread, and my water, and my flesh which I have killed for my shearers, and give [it] to men whom I know not whence they are?

12And David's young men turned their way, and went back, and came and reported to him according to all those words.

13And David said to 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.

14And one of [Nabal's] young men told Abigail, Nabal's wife, saying, Behold, David sent messengers out of the wilderness to bless our master; and he has insulted them.

15And the men were very good to us, and we were not hurt, neither missed we anything, as long as we companied with them, when we were in the fields.

16They were a wall to us both by night and day, all the while we were with them feeding the sheep.

17And now know and consider what thou wilt do, for evil is determined against our master, and against all his household; and he is such a son of Belial, that one cannot speak to him.
