Albert Barnes Commentary Exodus 17:7

"And he called the name of the place Massah, and Meribah, because of the striving of the children of Israel, and because they tempted Jehovah, saying, Is Jehovah among us, or not?" — Exodus 17:7 (ASV)

Massah ...Meribah - See the margin. On the importance of this lesson see our Lord’s words (Matthew 4:7).
