According to the command of God, the rock was to be smitten but once. Once smitten, it needed only to be spoken to; and, though it was more than thirty years afterward, it would yield forth its water. But Moses, provoked to anger by the murmurings and complainings of the people, transcended the Divine injunction, and though he had once smitten the rock, smote it again; yea, when he should have spoken to it only, smote it twice with his rod. This was his sin, for which God would not permit him to enter the promised land. Christ has been once smitten, and wo to those who smite him again! He has once offered himself a sacrifice, and once entered into the holy place, having finished his work of atonement, and made an end of sin, and superseded the sacrifices of the law. Henceforth, ye Jews, relinquish your burnt-offerings, your meat-offerings, your drink-offerings, your peace-offerings; and trust no longer in beasts, and birds, and flour, and oil; but in “the Lamb of God, that taketh away the sin of the world.” Crucify him afresh no more, O ye backsliders; for “there remaineth no other sacrifice for sin!” Smite him not again, lest he swear unto you in his wrath, as unto Moses, that ye shall not enter into his rest! II. Having spoken of the smiting, let us now look at the result, the flowing of the waters; a timely mercy to “the many thousands of Israel,” on the point of perishing in the desert; shadowing forth a far greater mercy, the flowing of living waters from the “spiritual rock,” which is Christ. In the death of our Redeemer, we see three infinite depths moved for the relief of human misery; the love of the Father, the merit of the Son, and the energy of the Holy Spirit. These are the depths of wonder whence arise the rivers of salvation. The waters flowed in the presence of the whole assembly. The agent was invisible, but his work was manifest. * * * * * * * * * * The water flowed in great abundance, filling the whole camp, and supplying all the people. Notwithstanding the immense number, and the greatness of their thirst, there was enough for each and for all. The streams ran in every direction to meet the sufferers, and their rippling murmur seemed to say—“Open thy mouth, and I will fill it.” Look to the cross! See there the gracious fountain opened, and streams of pardoning and purifying mercy flowing down the rock of Calvary, sweeping over the mount of Olives, and cleaving it asunder, to make a channel for the living waters to go out over the whole world, that God may be glorified among the Gentiles, and all the ends of the earth may see his salvation!
