1 Samuel 15:9

15:9 However, Saul and the army spared Agag, along with the best of the flock, the cattle, the fatlings, and the lambs, as well as everything else that was of value. They were not willing to slaughter them. But they did slaughter everything that was despised and worthless.

1 Samuel 17:20

17:20 So David got up early in the morning and entrusted the flock to someone else who would watch over it. After loading up, he went just as Jesse had instructed him. He arrived at the camp as the army was going out to the battle lines shouting its battle cry.
