Obedience
Israel Defeats the Amalekites
8 While the people of Israel were still at Rephidim, the warriors of Amalek attacked them. 9 Moses commanded Joshua, “Choose some men to go out and fight the army of Amalek for us. Tomorrow, I will stand at the top of the hill, holding the staff of God in my hand.”
10 So Joshua did what Moses had commanded and fought the army of Amalek. Meanwhile, Moses, Aaron, and Hur climbed to the top of a nearby hill. 11 As long as Moses held up the staff in his hand, the Israelites had the advantage. But whenever he dropped his hand, the Amalekites gained the advantage. 12 Moses’ arms soon became so tired he could no longer hold them up. So Aaron and Hur found a stone for him to sit on. Then they stood on each side of Moses, holding up his hands. So his hands held steady until sunset. 13 As a result, Joshua overwhelmed the army of Amalek in battle.
14 After the victory, the LORD instructed Moses, “Write this down on a scroll as a permanent reminder, and read it aloud to Joshua: I will erase the memory of Amalek from under heaven.” 15 Moses built an altar there and named it Yahweh-nissi (which means “the LORD is my banner”). 16 He said, “They have raised their fist against the LORD’s throne, so now the LORD will be at war with Amalek generation after generation
b. How he laid wait for him on the way when he came up from Egypt: This explains why the Amalekites should be judged so completely. Centuries before this the Amalekites were the first people to attack Israel after their escape from Egypt (Exodus 17).
i. Hundreds of years before, the LORD said He would bring this kind of judgment against Amalek: Then the LORD said to Moses, “Write this for a memorial in the book and recount it in the hearing of Joshua, that I will utterly blot out the remembrance of Amalek from under heaven.” And Moses built an altar and called its name, The-LORD-Is-My-Banner; for he said, “Because the LORD has sworn: the LORD will have war with Amalek from generation to generation.” (Exodus 17:14–16) Deuteronomy 25:17–19 repeats this idea.
ii. The Amalekites committed a terrible sin against Israel. When the nation was weak and vulnerable the Amalekites attacked the weakest and most vulnerable of the nation (Deuteronomy 25:18). They did this for no reasons except violence and greed. God hates it when the strong take cruel advantage over the weak, especially when the weak are His people.
iii. Though this happened more than 400 years before, God still held it against the Amalekites because time does not erase sin before God. Among men time should erase sin and the years should make us more forgiving to one another. But before God, time cannot atone for sin. Only the blood of Jesus Christ can erase sin, not time. In fact, it was time that the Amalekites were mercifully given opportunity to repent and they did not repent. The hundreds of years of hardened unrepentant hearts made them more guilty, not less guilty.
c. Now go and attack Amalek: God could have judged Amalek directly as He did against the cities of Sodom and Gomorrah. But God had a special purpose in this for His special nation, Israel. He wanted it to be a test of obedience for Saul and all of Israel. Plus, since Amalek’s sin against Israel was a military attack, God wanted to make the judgment fit the sin.
i. Would God call His people today to fight such a war of judgment? God has a completely different call for Christians under the New Covenant than He did for Israel under the Old Covenant (John 18:36).
ii. Though God no longer calls His people to take up arms as instruments of His judgment, it does not mean that God has stopped judging the nations. “But we cannot suppose, for a single moment, that the judgment of the nations is to be altogether relegated [appointed] to that final day. Throughout the history of the world the nations have been standing before Christ’s bar. Nineveh stood there, Babylon stood there, Greece and Rome stood there, Spain and France stood there, and Great Britain is standing there to-day. One after another has had the solemn word—depart, and they have passed into a destruction which has been absolute and terrible.” (Meyer
