7 And he called the name of the place Massah,  and Meribah, because of the chiding of the children of Israel, and because they tempted the Lord, saying, Is the Lord among us, or not?
7 And he called the place Massah
7 And he called the name of the place Massah
7 He named the place Massah (Testing-Place) and Meribah (Quarreling) because of the quarreling of the Israelites and because of their testing of God when they said, "Is God here with us, or not?"
7 So he called the name of the place Massah and Meribah, because of the contention of the children of Israel, and because they tempted the Lord, saying, "Is the Lord among us or not?"
7 Moses named the place Massah (which means "test") and Meribah (which means "arguing") because the people of Israel argued with Moses and tested the Lord by saying, "Is the Lord here with us or not?"

Commentary on Exodus 17:1-7
(Read Exodus 17:1-7)
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, 1 Corinthians 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.
