Throughout forty years Moses had striven to refrain from harshly addressing the people, knowing that if but a single time he lost patience, God would cause him to die in the desert. On this occasion, however, he was mastered by his rage, and shouted at Israel the words: "O ye madmen, ye stiffnecked ones, that desire to teach their teacher, ye that shoot upon your leaders with your arrows, do ye think that out of this rock that ye have chosen, we shall be able to bring forth water?
I vow that I shall let water flow out of that rock only that I have chosen." He addressed these harsh words not to a few among Israel, but to all the people, for God had brought the miracle to pass that the small space in front of the rock held all Israel. Carried away by anger, Moses still further forgot himself, and instead of speaking to the rock as God had commanded him, he struck a rock chosen by himself.
As Moses had not acted according to God's command, the rock did not at once obey, and sent forth only a few drops of water, so that the mockers cried: "Son of Amram, is this for the sucklings and for them that are weaned from the milk?" Moses now waxed angrier still, and for a second time smote the rock, from which gushed streams so mighty that many of his enemies me their death in the currents, and at the same time water poured out of all the stones and rocks of the desert.
God here upon said to Moses: "Thou and Aaron believed Me not, I forbade you to smite the rock, but thou didst smite it; ye sanctified Me not in the eyes of the children of Israel because ye did not fetch water out of any one of the rocks, as the people wished; ye trespassed against Me when ye said, 'Shall we bring forth water out of this rock?' and ye acted contrary to My command because ye did not speak to the rock as I had bidden ye.
I vow, therefore, that 'ye shall not bring this assembly into the land which I have given them,' and not until the Messianic time shall ye two lead Israel to the Holy Land." God furthermore said to Moses: "Thou shouldst have learned from the life of Ishmael to have greater faith in Me; I bade the well to spring up for him, even though he was only a single human being, on account of the merits of his father Abraham.
How much more than hadst thou a right to expect, thou who couldst refer to the merits of the three Patriarchs as well as to the people's own, for they accepted the Torah and obeyed many commandments. Yea, even from thine own experience shouldst thou have drawn greater faith in My will to aid Israel. When in Rephidim thou didst say to Me, 'They be almost ready to stone me,' did not I not reply to thee, 'Why dost thou accuse My children?
God with thy rod before the people, and thou shalt smite the rock, and there shall come water out of it.' If I wrought for them miracles such as these when they had not yet accepted the Torah, and did not yet have faith in Me, shouldst thou not have known how much more I would do for them now?"
