2 The Lord of armies says, I will give punishment to Amalek for what he did to Israel, fighting against him on the way when Israel came out of Egypt. 3 Go now and put Amalek to the sword, putting to the curse all they have, without mercy: put to death every man and woman, every child and baby at the breast, every ox and sheep, camel and ass.
Matthew Henry's Commentary on 1 Samuel 15:2-3
Commentary on 1 Samuel 15:1-9
(Read 1 Samuel 15:1-9)
The sentence of condemnation against the Amalekites had gone forth long before, Revelation 18:4. As the commandment had been express, and a test of Saul's obedience, his conduct evidently was the effect of a proud, rebellious spirit. He destroyed only the refuse, that was good for little. That which was now destroyed was sacrificed to the justice of God.
