1 Samuel 15:10-15

Then came the word of Jehovah unto Samuel, saying, It repenteth me that I have set up Saul to be king; for he is turned back from following me, and hath not performed my commandments. And Samuel was wroth; and he cried unto Jehovah all night. And Samuel rose early to meet Saul in the morning; and it was told Samuel, saying, Saul came to Carmel, and, behold, he set him up a monument, and turned, and passed on, and went down to Gilgal. And Samuel came to Saul; and Saul said unto him, Blessed be thou of Jehovah: I have performed the commandment of Jehovah. And Samuel said, What meaneth then this bleating of the sheep in mine ears, and the lowing of the oxen which I hear? 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 Jehovah thy God; and the rest we have utterly destroyed.
