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 15:19

15:19 Why haven’t you obeyed the Lord? Instead you have greedily rushed upon the plunder! You have done what is wrong in the Lord’s estimation.”
