of the rock. The elders were to be eye-witnesses of the miracle, that they might bear their testimony to it before the unbelieving people, “ne dicere possint, jam ab antiquis temporibus fontes ibi fuisse” (Rashi). Jehovah's standing before Moses upon the rock, signified the gracious assistance of God. לפני עמד frequently denotes the attitude of a servant when standing before his master, to receive and execute his commands. Thus Jehovah condescended to come to the help of Moses, and assist His people with His almighty power. His gracious presence caused water to flow out of the hard dry rock, though not till Moses struck it with his staff, that the people might acknowledge him afresh as the possessor of supernatural and miraculous powers.

The expansion of this tribe, that was descended from a grandson of Esau (see Gen 36:12), into so great a power even in the Mosaic times, is perfectly conceivable, if we imagine the process to have been analogous to that which we have already described in the case of the leading branches of the Edomites, who had grown into a powerful nation through the subjugation and incorporation of the earlier population of Mount Seir. The Amalekites had no doubt come to the neighbourhood of Sinai for the same reason for which, even in the present day, the Bedouin Arabs leave the lower districts at the beginning of summer, and congregate in the mountain regions of the Arabian peninsula, viz., because the grass is dried up in the former, whereas in the
