Exodus 17:5,6

Go before the people Though they spoke of stoning him. He must take his rod with him, not to summon some plague to chastise them, but to fetch water for their supply. O the wonderful patience and forbearance of God toward provoking sinners! He maintains those that are at war with him, and reaches out the hand of his bounty to those that lift up the heel against him. If God had only showed Moses a fountain of water in the wilderness, as he did to Hagar, not far from hence, (Genesis 21:19,) that had been a great favour; but 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. He directed Moses whither to go, appointed him to take of the elders of Israel with him, to be witnesses of what was done, ordered him to smite the rock, which he did, and immediately water came out of it in great abundance, which ran throughout the camp in streams and rivers, Psalms 78:15. God showed his care of his people in giving them water when they wanted it; his own power in fetching it out of a rock, and put an honour upon Moses in appointing the water to flow out upon his smiting of the rock. This fair water that came out of the rock is called honey and oil, (Deuteronomy 32:13,) because the people's thirst made it doubly pleasant; coming when they were in extreme want. It is probable that the people digged canals for the conveyance of it, and pools for the reception of it. Let this direct us to live in a dependance, 1st, Upon God's providence, even in the greatest straits and difficulties; and, 2d, Upon Christ's grace; that rock was Christ, 1 Corinthians 10:4. The graces and comforts of the Spirit are compared to rivers of living waters, John 7:38; John 4:14. These flow from Christ. And nothing will supply the needs and satisfy the desires of a soul but water out of this rock. A new name was, upon this occasion, given to the place, preserving the remembrance of their murmuring; Massah Temptation, because they tempted God; Meribah Strife, because they chid with Moses. Several commentators have here quoted the following passage from Shaw's Travels, as a wonderful confirmation of this great miracle: “Here (in the plain of Rephidim) we still see that extraordinary antiquity, the rock of Meribah, which hath continued down to this day, without the least injury from time or accident. It is a block of granite marble, about six yards square, lying tottering as it were, and loose in the middle of the valley, and seems to have formerly belonged to mount Sinai, which hangs in a variety of precipices all over this plain. The waters which gushed out, and the stream which followed, (Psalms 78:20,) have hollowed, across one corner of this rock, a channel about two inches deep and twenty wide, appearing to be incrustated all over, like the inside of a teakettle that had been long in use. Besides several mossy productions that are still preserved by the dew, we see all over the channel a great number of holes, some of them four or five inches deep, and one or two in diameter, the lively and demonstrative tokens of their having been formerly so many fountains. It likewise may be further observed, that art or chance could by no means be concerned in the contrivance; for every circumstance points out to us a miracle; and, in the same manner with the rent in the rock of mount Calvary, at Jerusalem, never fails to produce a religious surprise in all who see it. The Arabs, who were our guard, were ready to stone me for attempting to break off a corner of it.” Shaw's Travels, pp. 252, 253.
