5 And the Lord said unto Moses, Go on before the people, and take with thee of the elders of Israel; and thy rod, wherewith thou smotest the river, take in thine hand, and go.
6 Behold, I will stand before thee there upon the rock in Horeb; and thou shalt smite the rock, and there shall come water out of it, that the people may drink. And Moses did so in the sight of the elders of Israel.
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?
As with the story of the manna and the quail, the account given in today’s verses are repeated with more detail in Numbers. And, once again, there is a key difference between the account given here and the one in Numbers. Here God tells Moses “thou shalt smite the rock,” whereas in Numbers he is told only to “speak ye unto the rock.” This matters, because many people have read the Numbers account and interpreted Moses’s striking of the rock as the breach of faith for which God prohibited his entry to the Promised Land. Obviously that assumption would be inaccurate if today’s version of the story is the correct one, in which the Lord had actually instructed Moses to strike the rock. In that case, Moses’s failure must have been something else.
Personally, I see an argument from a narrative perspective as to why today’s account might be the correct one. In verse 5 God mentions that this is the rod “wherewith thou smotest the river,” referring to when Moses smote the river in Egypt and turned it to blood. The staff has a history of being used to smite, both literally and figuratively, and also working wonders upon the waters. It would therefore be thematically consistent for it to once again be used to smite the rock and miraculously bring forth water, all according to God’s wishes.
Moving on from the debate of which account is more accurate, though, let us note the clear symbolism in this verse. Moses smote the rock and water came out of it, providing life-sustenance to the people. In later references we will be told that the rock clave in two, causing a breach from which the water would flow. This immediately calls to mind the spear that pierced the side of Christ, creating the opening from which the water flowed out of his body. And this, of course, is symbolic of the spirit Christ is able to plant in all of our hearts through his sacrifice. This spirit is frequently referred to as a life-sustaining wellspring, constantly refreshing us, just as Israel was refreshed by this miracle in the desert.
