6 Saul said to the Kenites , "Go , depart , go down from among the Amalekites , so that I do not destroy you with them; for you showed kindness to all the sons of Israel when they came up from Egypt ." So the Kenites departed from among the Amalekites .
Matthew Henry's Commentary on 1 Samuel 15:6
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.
