Saul said, They have brought them from the Amalekites: for the people spared the best of the sheep and of the oxen, to sacrifice to Yahweh your God; and the rest we have utterly destroyed.
"Saul was an impetuous person who wanted to take matters into his own hands rather than trusting the Lord. He had the opposite of the proper covenant mentality. His sin was so serious that there could be no atonement for it. This is similar to Eli’s sons, for whose sins no atonement was available. Their sin resulted in a change of order, from Eli to Samuel. In Saul’s case the change in order was from Saul to David." [Note: Martin, p. 35.]
