1. Samuel 15:28

War with Amalek. Saul's Disobedience and Rejection - 1 Samuel 15 As Saul had transgressed the commandment of God which was given to him through Samuel, by the sacrifice which he offered at Gilgal in the war with the Philistines at the very commencement of his reign, and had thereby drawn upon himself the threat that his monarchy should not be continued in perpetuity (Sa1 13:13-14); so his disobedience in the war against the Amalekites was followed by his rejection on the part of God. The Amalekites were the first heathen nation to attack the Israelites after their deliverance out of Egypt, which they did in the most treacherous manner on their journey from Egypt to Sinai; and they had been threatened by God with extermination in consequence. This Moses enjoined upon Joshua, and also committed to writing, for the Israelites to observe in all future generations (Exo 17:8-16). As the Amalekites afterwards manifested the same hostility to the people of God which they had displayed in this first attack, on every occasion which appeared favourable to their ravages, the Lord instructed Samuel to issue the command to Saul, to wage war against Amalek, and to smite man and beast with the ban, i.e., to put all to death (Sa1 15:1-3). But when Saul had smitten them, he not only left Agag the king alive, but spared the best of the cattle that he had taken as booty, and merely executed the ban upon such animals as were worthless (Sa1 15:4-9). He was rejected by the Lord for this disobedience, so that he was to be no longer king over Israel. His rejection was announced to him by Samuel (Sa1 15:10-23), and was not retracted in spite of his prayer for the forgiveness of his sin (Sa1 15:24-35). In fact, Saul had no excuse for this breach of the divine command; it was nothing but open rebe…

In this chapter we have the final rejection of Saul from being king, for his disobedience to God's command in not utterly destroying the Amalekites. By his wars and victories he hoped to magnify and perpetuate his own name and honour, but, by his mismanagement of them, he ruined himself, and laid his honour in the dust. Here is, I. The commission God gave him to destroy the Amalekites, with a command to do it utterly (Sa1 15:1-3). II. Saul's preparation for this expedition (Sa1 15:4-6). III. His success, and partial execution of this commission (Sa1 15:7-9). IV. His examination before Samuel, and sentence passed upon him, notwithstanding the many frivolous pleas he made to excuse himself (v. 10-31). V. The slaying of Agag (Sa1 15:32, Sa1 15:33). VI. Samuel's final farewell to Saul (Sa1 15:34, Sa1 15:35).

15:28 Saul soon discovered who this someone else was (18:8-9; cp. ch 16).
