Thus says LORD of hosts, I have remembered that which Amalek did to Israel, how he set himself against him in the way when he came up out of Egypt.

Now go and smite Amalek, and utterly destroy all that they have, and spare them not, but kill both man and woman, infant and suckling, ox and sheep, camel and donkey.

And Saul came to the city of Amalek, and laid wait in the valley.

And Saul said to Samuel, Yes, I have obeyed the voice of LORD, and have gone the way which LORD sent me, and have brought Agag the king of Amalek, and have utterly destroyed the Amalekites.

Because thou obeyed not the voice of LORD, and did not execute his fierce wrath upon Amalek, therefore LORD has done this thing to thee this day.
