1 All the congregation of the children of Israel traveled from the wilderness of Sin, by their journeys, according to the LORD’s commandment, and encamped in Rephidim; but there was no water for the people to drink. 2 Therefore the people quarreled with Moses, and said, “Give us water to drink.” Moses said to them, “Why do you quarrel with me? Why do you test the LORD?” 3 The people were thirsty for water there; and the people murmured against Moses, and said, “Why have you brought us up out of Egypt, to kill us, our children, and our livestock with thirst?” 4 Moses cried to the LORD, saying, “What shall I do with these people? They are almost ready to stone me.” 5 The LORD said to Moses, “Walk on before the people, and take the elders of Israel with you, and take the rod in your hand with which you struck the Nile, and go. 6 Behold, I will stand before you there on the rock in Horeb. You shall strike the rock, and water will come out of it, that the people may drink.” Moses did so in the sight of the elders of Israel. 7 He called the name of the place Massah, and Meribah, because the children of Israel quarreled, and because they tested the LORD, saying, “Is the LORD amongst us, or not?” 8 Then Amalek came and fought with Israel in Rephidim. 9 Moses said to Joshua, “Choose men for us, and go out, fight with Amalek. Tomorrow I will stand on the top of the hill with God’s rod in my hand.” 10 So Joshua did as Moses had told him, and fought with Amalek; and Moses, Aaron, and Hur went up to the top of the hill. 11 When Moses held up his hand, Israel prevailed. When he let down his hand, Amalek prevailed. 12 But Moses’ hands were heavy; and they took a stone, and put it under him, and he sat on it. Aaron and Hur held up his hands, the one on the one side, and the other on the other side. His hands were steady until sunset. 13 Joshua defeated Amalek and his people with the edge of the sword. 14 The LORD said to Moses, “Write this for a memorial in a book, and rehearse it in the ears of Joshua: that I will utterly blot out the memory of Amalek from under the sky.” 15 Moses built an altar, and called its name the LORD our Banner. 16 He said, “The LORD has sworn: ‘The LORD will have war with Amalek from generation to generation.’”

Verses 1–7
The children of Israel journeyed according to the commandment of the Lord, led by the pillar of cloud and fire, yet they came to a place where there was no water for them to drink. We may be in the way of duty, yet may meet with troubles, which Providence brings us into, for the trial of our faith, and that God may be glorified in our relief. They began to question whether God was with them or not. This is called their “tempting God,” which signifies distrust of him after they had received such proofs of his power and goodness. Moses mildly answered them. It is folly to answer passion with passion; that makes bad worse. God graciously appeared to help them. How wonderful the patience and forbearance of God toward provoking sinners! That he might show his power as well as his pity, and make it a miracle of mercy, he gave them water out of a rock. God can open fountains for us where we least expect them. Those who, in this wilderness, keep to God’s way, may trust him to provide for them. Also, let this direct us to depend on Christ’s grace. The apostle says, that Rock was Christ, 1Co 10:4, it was a type of him. While the curse of God might justly have been executed upon our guilty souls, behold the Son of God is smitten for us. Let us ask and receive. There was a constant, abundant supply of this water. Numerous as believers are, the supply of the Spirit of Christ is enough for all. The water flowed from the rock in streams to refresh the wilderness, and attended them on their way towards Canaan; and this water flows from Christ, through the ordinances, in the barren wilderness of this world, to refresh our souls, until we come to glory. A new name was given to the place, in remembrance, not of the mercy of their supply, but of the sin of their murmuring: “Massah,” Temptation, because they tempted God; “Meribah,” Strife, because they chid with Moses. Sin leaves a blot upon the name.
Verses 8–16
Israel engaged with Amalek in their own necessary defence. God makes his people able, and calls them to various services for the good of his church. Joshua fights, Moses prays, both minister to Israel. The rod was held up, as the banner to encourage the soldiers. Also to God, by way of appeal to him. Moses was tired. The strongest arm will fail with being long held out; it is God only whose hand is stretched out still. We do not find that Joshua’s hands were heavy in fighting, but Moses’ hands were heavy in praying; the more spiritual any service is, the more apt we are to fail and flag in it. To convince Israel that the hand of Moses, whom they had been chiding, did more for their safety than their own hands, his rod than their sword, the success rises and falls as Moses lifts up or lets down his hands. The church’s cause is more or less successful, as her friends are more or less strong in faith, and fervent in prayer. Moses, the man of God, is glad of help. We should not be shy, either of asking help from others, or of giving help to others. The hands of Moses being thus stayed, were steady till the going down of the sun. It was great encouragement to the people to see Joshua before them in the field of battle, and Moses above them on the hill. Christ is both to us; our Joshua, the Captain of our salvation, who fights our battles, and our Moses, who ever lives, making intercession above, that our faith fail not. Weapons formed against God’s Israel cannot prosper long, and shall be broken at last. Moses must write what had been done, what Amalek had done against Israel; write their bitter hatred; write their cruel attempts; let them never be forgotten, nor what God had done for Israel in saving them from Amalek. Write what should be done; that in process of time Amalek should be totally ruined and rooted out. Amalek’s destruction was typical of the destruction of all the enemies of Christ and his kingdom.
