Till thy people pass over—i.e., cross the frontier of the Canaanites, and enter their country. There is no need to suppose that Moses had as yet any distinct idea of the place where the frontier would be crossed.

The mighty men of Moab - The physical strength and great stature of the Moabites are noted in other passages: see Jeremiah 48:29, Jeremiah 48:41.

Canaan - The name in this, as in many passages of Genesis, designates the whole of Palestine: and is used of course with reference to the promise to Abraham. It was known to the Egyptians, and occurs frequently on the monuments as Pa-kanana, which applies, if not to the whole of Palestine, yet to the northern district under Lebanon, which the Phoenicians occupied and called "Canaan."

Ex 15:1-27. Song of Moses.

1. Then sang Moses and the children of Israel—The scene of this thanksgiving song is supposed to have been at the landing place on the eastern shore of the Red Sea, at Ayoun Musa, "the fountains of Moses." They are situated somewhat farther northward along the shore than the opposite point from which the Israelites set out. But the line of the people would be extended during the passage, and one extremity of it would reach as far north as these fountains, which would supply them with water on landing. The time when it was sung is supposed to have been the morning after the passage. This song is, by some hundred years, the oldest poem in the world. There is a sublimity and beauty in the language that is unexampled. But its unrivalled superiority arises not solely from the splendor of the diction. Its poetical excellencies have often drawn forth the admiration of the best judges, while the character of the event commemorated, and its being prompted by divine inspiration, contribute to give it an interest and sublimity peculiar to itself.

I will sing unto the Lord, for he hath triumphed gloriously—Considering the state of servitude in which they had been born and bred, and the rude features of character which their subsequent history often displays, it cannot be supposed that the children of Israel generally were qualified to commit to memory or to appreciate the beauties of this inimitable song. But they might perfectly understand its pervading strain of sentiment; and, with the view of suitably improving the occasion, it was thought necessary that all, old and young, should join their united voices in the rehearsal of its words. As every individual had cause, so every individual gave utterance to his feelings of gratitude.

by the greatness of thine arm they shall be as still as a stone; awed by the power of God, visible in what he had done for the Israelites, and upon their enemies; they should be like stocks and stones, immovable, have no power to act, nor stir a foot in their own defence, and against Israel, come to invade and possess their land; nor in the least molest them, or stop them in their passage over Jordan, or dispute it with them, but stand like persons thunderstruck, and as stupid as stones, not having any spirit or courage left in them:

till thy people pass over, O Lord, till the people pass over, which thou hast purchased; pass over the brook of Arnon, and the ford of Jabbok, according to the Targum of Jonathan; or the ford of Jabbok, and the ford of Jordan, according to the Jerusalem Targum; the river of Jordan is doubtless literally meant, at least chiefly; and the accomplishment of this prediction may be seen in Joshua 3:15 which was an emblem of the quiet passage of Christ's purchased people, through the ford or river of death, to the Canaan of everlasting rest and happiness: Christ's people are purchased by him, who is able to make the purchase, and had a right to do it, and has actually made it, by giving his flesh, shedding his blood, laying down his life, and giving himself a ransom price for them: these do, and must pass over Jordan, or go through the cold stream of death; it is the way of all the earth, of good men as well as others; it is a passage from one world to another; and there is no getting to the heavenly Canaan without going this way, or through this ford; and all the Lord's purchased people, like Israel, clean pass over through it, not one are left in it; their bodies are raised again, their souls are reunited to them, and both come safe to heaven and happiness: and, for the most part, they have a quiet and easy passage, the enemy is not suffered to disturb them, neither the sins and corruptions of their nature, nor an evil heart of unbelief, nor Satan with his temptations; and the terrors of death are taken away from them; so that they can sit and sing on the shores of eternity, in the view of death and another world, saying, death, where is thy sting? grave, where is thy victory? &c. and this is to be ascribed to the greatness of Jehovah's arm, to his almighty power, on which they lean, and go on comfortably in the wilderness; and by this they are carried safely through death to glory, and it is owing to this that the enemy and the avenger are stilled.
