1 Samuel 15:13-15

When Samuel came to Saul, Saul said, “May the LORD bless you! I have obeyed the LORD’s commands.” But Samuel said, “Then why do I hear cattle mooing and sheep bleating?” Saul answered, “The soldiers took them from the Amalekites. They saved the best sheep and cattle to offer as sacrifices to the LORD your God, but we destroyed all the other animals.”
