Exodus 17:6

I will stand before thee there, upon the rock in Horeb - The rock, הצור hatstsur. It seems as if God had directed the attention of Moses to a particular rock, with which he was well acquainted; for every part of the mount and its vicinity must have been well known to Moses during the time he kept Jethro's flocks in those quarters. Dr. Priestley has left the following sensible observations upon this miracle: -

"The luminous cloud, the symbol of the Divine presence, would appear on the rock, and Horeb was probably a part of the same mountain with Sinai. This supply of water, on Moses only striking the rock, where no water had been before nor has been since, was a most wonderful display of the Divine power. The water must have been in great abundance to supply two millions of persons, which excluded all possibility of artifice or imposture in the case. The miracle must also have been of some continuance, no doubt so long as they continued in that neighborhood, which was more than a year. There are sufficient traces of this extraordinary miracle remaining at this day. This rock has been visited, drawn, and described by Dr. Shaw, Dr. Pocock, and others; and holes and channels appear in the stone, which could only have been formed by the bursting out and running of the water. No art of man could have done it, if any motive could be supposed for the undertaking in such a place as this."

This miracle has not escaped the notice of the ancient Greek poets. Callimachus represents Rhea bringing forth water from a rock in the same way, after the birth of Jupiter.

Πληξεν ορος σκηπτρῳ, το δε οἱ δεχα πουλυ διεστη.

Εκ δ' εχεεν μεγα χευμα.

Hymn ad Jov., ver. 31.

- With her scepter struck

The yawning cliff; from its disparted height

Adown the mount the gushing torrent ran.

The rock mentioned above has been seen and described by Norden, p. 144, 8vo.; Dr. Shaw, p. 314, 4th., where there is an accurate drawing of it; Dr. Pocock, vol. i., p. 143, etc., where the reader may find some fine plates of Mount Horeb and Sinai, and four different views of the wonderful rock of Meribah. It is a vast block of red granite, fifteen feet long, ten broad, and twelve high. See Dr. Shaw's account at the end of Exodus. My nephew, who visited this rock in 1823, confirms the account of the preceding travelers, and has brought a piece of this wonderful stone. The granite is fine, and the quartz mica, and feldspar equally mixed in it. This rock or block of granite is the only type of Christ now existing.

The rock in Horeb - (a rock situated, according to Arab tradition, in Wady Feiran. Horeb was a name given to the whole desert of Sinai and subsequently attached to the mountain. Palmer).

It is questioned whether the water thus supplied ceased with the immediate occasion; see 1 Corinthians 10:4, the general meaning of which appears to be that their wants were ever supplied from Him, of whom the rock was but a symbol, and who accompanied them in all their wanderings.
