I Samuel 15:1-3, 8-9, 11, 19-22

Samuel also said to Saul, “The LORD sent me to anoint you king over His people, over Israel. Now therefore, heed the voice of the words of the LORD. Thus says the LORD of hosts: ‘I will punish Amalek for what he did to Israel, how he ambushed him on the way when he came up from Egypt. Now go and attack Amalek, and utterly destroy all that they have, and do not spare them. But kill both man and woman, infant and nursing child, ox and sheep, camel and donkey.’ ”

He also took Agag king of the Amalekites alive, and utterly destroyed all the people with the edge of the sword. But Saul and the people spared Agag and the best of the sheep, the oxen, the fatlings, the lambs, and all that was good, and were unwilling to utterly destroy them. But everything despised and worthless, that they utterly destroyed.

“I greatly regret that I have set up Saul as king, for he has turned back from following Me, and has not performed My commandments.” And it grieved Samuel, and he cried out to the LORD all night.

Why then did you not obey the voice of the LORD? Why did you swoop down on the spoil, and do evil in the sight of the LORD?” And Saul said to Samuel, “But I have obeyed the voice of the LORD, and gone on the mission on which the LORD sent me, and brought back Agag king of Amalek; I have utterly destroyed the Amalekites. But the people took of the plunder, sheep and oxen, the best of the things which should have been utterly destroyed, to sacrifice to the LORD your God in Gilgal.” So Samuel said: “Has the LORD as great delight in burnt offerings and sacrifices, As in obeying the voice of the LORD? Behold, to obey is better than sacrifice, And to heed than the fat of rams.
