Exodus 17:2-9

Verse 2

Why chide ye with me? - God is your leader, complain to him; Wherefore do ye tempt the Lord? As he is your leader, all your murmurings against me he considers as directed against himself; why therefore do ye tempt him? Has he not given you sufficient proofs that he can destroy his enemies and support his friends? And is he not among you to do you good? Exo 17:7. Why therefore do ye doubt his power and goodness, and thus provoke him to treat you as his enemies?
Verse 3

And the people murmured - The reader must not forget what has so often been noted relating to the degraded state of the minds of the Israelites. A strong argument however may be drawn from this in favor of their supernatural escape from Egypt. Had it been a scheme concerted by the heads of the people, provision would necessarily have been made for such exigencies as these. But as God chose to keep them constantly dependent upon himself for every necessary of life, and as they had Moses alone as their mediator to look to, they murmured against him when brought into straits and difficulties, regretted their having left Egypt, and expressed the strongest desire to return. This shows that they had left Egypt reluctantly; and as Moses and Aaron never appear to have any resources but those which came most evidently in a supernatural way, therefore the whole exodus or departure from Egypt proves itself to have been no human contrivance, but a measure concerted by God himself.
Verse 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.

Prior.

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.
Verse 7

He called the name of the place Massah, and Meribah - מסה Massah signifies temptation or trial; and מריבה Meribah, contention or litigation. From 1Cor 10:4, we learn that this rock was a type of Christ, and their drinking of it is represented as their being made partakers of the grace and mercy of God through Christ Jesus; and yet many who drank fell and perished in the wilderness in the very act of disobedience! Reader, be not high minded, but fear! On the smiting of the rock by the rod of Moses, Mr. Ainsworth has the following pious note: "This rock signified Christ, and is therefore called a spiritual Rock, 1Cor 10:4. He being smitten with Moses's rod, and bearing the curse of the law for our sins, and by the preaching of the Gospel crucified among his people, Gal 3:1, from him floweth the spiritual drink wherewith all believing hearts are refreshed." Joh 7:37, and Isa 53:1-3.
Verse 8

Then came Amalek, and fought with Israel - The Amalekites seem to have attacked the Israelites in the same way and through the same motives that the wandering Arabs attack the caravans which annually pass through the same desert. It does not appear that the Israelites gave them any kind of provocation, they seem to have attacked them merely through the hopes of plunder. The Amalekites were the posterity of Amalek, one of the dukes of Eliphaz, the son of Esau, and consequently Israel's brother, Gen 36:15, Gen 36:16.

Fought with Israel - In the most treacherous and dastardly manner; for they came at the rear of the camp, smote the hindmost of the people, even all that were feeble behind, when they were faint and weary; see Deu 25:18. The baggage, no doubt, was the object of their avarice; but finding the women, children, aged and infirm persons, behind with the baggage, they smote them and took away their spoils.
Verse 9

Moses said unto Joshua - This is the first place in which Joshua the son of Nun is mentioned: the illustrious part which he took in Jewish affairs, till the settlement of his countrymen in the promised land, is well known. He was captain-general of the Hebrews under Moses; and on this great man's death he became his successor in the government. Joshua was at first called Hoshea, Num 13:16, and afterwards called Joshua by Moses. Both in the Septuagint and Greek Testament he is called Jesus: the name signifies Savior; and he is allowed to have been a very expressive type of our blessed Lord. He fought with and conquered the enemies of his people, brought them into the promised land, and divided it to them by lot. The parallel between him and the Savior of the world is too evident to require pointing out.

Top of the hill - Probably some part of Horeb or Sinai, to which they were then near.
