Exodus 17:7

And he called the name of the place Massah (temptation) and Meribah (strife) because of the chiding of the children of Israel, and because they tempted the Lord, saying, Is the Lord among us or not? So that had been their real transgression, the doubts as to the presence of the Lord with their army, the pillar of cloud and of fire apparently not being sufficient any more to uphold their faith. The events here narrated were considered an example of warning throughout the time of the Old Testament as well as in the New, Psalms 95:8; Hebrews 4:9. And as it was Christ who journeyed with His people at that time and strengthened the faith of those who noted His presence in the miracle, so it is He who gives us at all times the true spiritual water to quench the thirst of our souls.
