1 Samuel 15:13–15

13 And Samuel came to Saul: and Saul said unto him, Blessed be thou of the Lord: I have performed the commandment of the Lord. 14 And Samuel said, What meaneth then this bleating of the sheep in mine ears, and the lowing of the oxen which I hear? 15 And Saul said, They have brought them from the Amalekites: for the people spared the best of the sheep and of the oxen, to sacrifice unto the Lord thy God; and the rest we have utterly destroyed.
