Ephraem the Syrian
Moses constructed an altar, and the Lord demonstrated His power against Amalek, the most militaristic of nations. He made it apparent to all nations weaker than Amalek that if they engaged in battle with the Hebrews, they would face defeat just as the Amalekites did. Although these nations recognized that their fate, both salvation and ruin, rested with God, they failed to seek the Hebrews’ protection as a gesture of goodwill. Consequently, God instructed the Israelites to extend their right hand to the cities prior to confronting them in battle.
