The Deliverance of Israel Celebrated.

1 When Israel went out of Egypt, the house of Jacob from a people of strange language;   2 Judah was his sanctuary, and Israel his dominion.   3 The sea saw it, and fled: Jordan was driven back.   4 The mountains skipped like rams, and the little hills like lambs.   5 What ailed thee, O thou sea, that thou fleddest? thou Jordan, that thou wast driven back?   6 Ye mountains, that ye skipped like rams; and ye little hills, like lambs?   7 Tremble, thou earth, at the presence of the Lord, at the presence of the God of Jacob;   8 Which turned the rock into a standing water, the flint into a fountain of waters.

The psalmist is here remembering the days of old, the years of the right hand of the Most High, and the wonders which their fathers told them of (Judg. vi. 13), for time, as it does not wear out the guilt of sin, so it should not wear out the sense of mercy. Let it never be forgotten,

I. That God brought Israel out of the house of bondage with a high hand and a stretched-out arm: Israel went out of Egypt, v. 1. They did not steal out clandestinely, nor were they driven out, but fairly went out, marched out with all the marks of honour; they went out from a barbarous people, that had used them barbarously, from a people of a strange language, Ps. lxxxi. 5. The Israelites, it seems, preserved their own language pure among them, and cared not for learning the language of their oppressors. By this distinction from them they kept up an earnest of their deliverance.

II. That he himself framed their civil and sacred constitution (v. 2): Judah and Israel were his sanctuary, his dominion. When he delivered them out of the hand of their oppressors it was that they might serve him both in holiness and in righteousness, in the duties of religious worship and in obedience to the moral law, in their whole conversation. Let my people go, that they may serve me. In order to this, 1. He set up his sanctuary among them, in which he gave them the special tokens of his presence with them and promised to receive their homage and tribute. Happy are the people that have God's sanctuary among them (see Exod. xxv. 8, Ezek. xxxvii. 26), much more those that, like Judah here, are his sanctuaries, his living temples, on whom Holiness to the Lord is written. 2. He set up his dominion among them, was himself their lawgiver and their judge, and their government was a theocracy: The Lord was their King. All the world is God's dominion, but Israel was so in a peculiar manner. What is God's sanctuary must be his dominion. Those only have the privileges of his house that submit to the laws of it; and for this end Christ has redeemed us that he might bring us into God's service and engage us for ever in it.

III. That the Red Sea was divided before them at their coming out of Egypt, both for their rescue and the ruin of their enemies; and the river Jordan, when they entered into Canaan, for their honour, and the confusion and terror of their enemies (v. 3): The sea saw it, saw there that Judah was God's sanctuary, and Israel his dominion, and therefore fled; for nothing could be more awful. It was this that drove Jordan back, and was an invincible dam to his streams; God was at the head of that people, and therefore they must give way to them, must make room for them, they must retire, contrary to their nature, when God speaks the word. To illustrate this the psalmist asks, in a poetical strain (v. 5), What ailed thee, O thou sea! that thou fleddest? And furnishes the sea with an answer (v. 7); it was at the presence of the Lord. This is designed to express, 1. The reality of the miracle, that it was not by any power of nature, or from any natural cause, but it was at the presence of the Lord, who gave the word. 2. The mercy of the miracle: What ailed thee? Was it in a frolic? Was it only to amuse men? No; it was at the presence of the God of Jacob; it was in kindness to the Israel of God, for the salvation of that chosen people, that God was thus displeased against the rivers, and his wrath was against the sea, as the prophet speaks, Hab. iii. 8-13; Isa. li. 10; lxvi. 11, &c. 3. The wonder and surprise of the miracle. Who would have thought of such a thing? Shall the course of nature be changed, and its fundamental laws dispensed with, to serve a turn for God's Israel? Well may the dukes of Edom be amazed and the mighty men of Moab tremble, Exod. xv. 15. 4. The honour hereby put upon Israel, who are taught to triumph over the sea, and Jordan, as unable to stand before them. Note, There is no sea, no Jordan, so deep, so broad, but, when God's time shall come for the redemption of his people, it shall be divided and driven back if it stand in their way. Apply this, (1.) To the planting of the Christian church in the world. What ailed Satan and the powers of darkness, that they trembled and truckled as they did? Mark i. 34. What ailed the heathen oracles, that they were silenced, struck dumb, struck dead? What ailed their idolatries and witchcrafts, that they died away before the gospel, and melted like snow before the sun? What ailed the persecutors and opposers of the gospel, that they gave up their cause, hid their guilty heads, and called to rocks and mountains for shelter? Rev. vi. 15. It was at the presence of the Lord, and that power which went along with the gospel. (2.) To the work of grace in the heart. What turns the stream in a regenerate soul? What ails the lusts and corruptions, that they fly back, that the prejudices are removed and the whole man has become new? It is at the presence of God's Spirit that imaginations are cast down, 2 Cor. x. 5.

IV. That the earth shook and trembled when God came down on Mount Sinai to give the law (v. 4): The mountains skipped like rams, and then the little hills might well be excused if they skipped like lambs, either when they are frightened or when they sport themselves. The same power that fixed the fluid waters and made them stand still shook the stable mountains and made them tremble for all the powers of nature are under the check of the God of nature. Mountains and hills are, before God, but like rams and lambs; even the bulkiest and the most rocky are as manageable by him as they are by the shepherd. The trembling of the mountains before the Lord may shame the stupidity and obduracy of the children of men, who are not moved at the discoveries of his glory. The psalmist asks the mountains and hills what ailed them to skip thus; and he answers for them, as for the seas, it was at the presence of the Lord, before whom, not only those mountains, but the earth itself, may well tremble (v. 7), since it has lain under a curse for man's sin. See Ps. civ. 32; Isa. lxiv. 3, 4. He that made the hills and mountains to skip thus can, when he pleases, dissipate the strength and spirit of the proudest of his enemies and make them tremble.

V. That God supplied them with water out of the rock, which followed them through the dry and sandy deserts. Well may the earth and all its inhabitants tremble before that God who turned the rock into a standing water (v. 8), and what cannot he do who did that? The same almighty power that turned waters into a rock to be a wall to Israel (Exod. xiv. 22) turned the rock into waters to be a well to Israel: as they were protected, so they were provided for, by miracles, standing miracles; for such was the standing water, that fountain of waters into which the rock, the flinty rock, was turned, and that rock was Christ, 1 Cor. x. 4. For he is a fountain of living waters to his Israel, from whom they receive grace for grace.
