In the mountain of thine inheritance - See Exodus 15:13.

Thou shalt bring them in - By thy strength and mercy alone shall they get the promised inheritance.

And plant them - Give them a fixed habitation in Canaan, after their unsettled wandering life in the wilderness.

In the mountain - Meaning Canaan, which was a very mountainous country, Deuteronomy 11:11; or probably Mount Zion, on which the temple was built. Where the pure worship of God was established, there the people might expect both rest and safety. Wherever the purity of religion is established and preserved, and the high and the low endeavor to regulate their lives according to its precepts, the government of that country is likely to be permanent.

Thou shalt bring them in,.... Into the land of Canaan, which is often ascribed to the Lord, as well as his bringing them out of the land of Egypt, see Deuteronomy 8:8,

and plant them in the mountain of thine inheritance; in the country which he chose for the inheritance of his people and himself; one part of which was very mountainous, called the hill country of Judea, and especially Jerusalem, round about which mountains were; and particular respect may be had to Mount Moriah and Zion, on which the temple afterwards stood, and which was called the mountain of the Lord's house, and seems to be pointed at in the following account: here Israel is compared to a vine as elsewhere, which the Lord took out of Egypt and planted in the land of Canaan, where it took root and was settled, see Psalm 80:8.

in the place, O Lord, which thou hast made for thee to dwell in; that is, which he had appointed for his habitation; for as yet neither the tabernacle nor temple were built, in which he afterwards dwelt: in this sense the word "made" is used in Proverbs 16:4.

in the sanctuary, O Lord, which thy hands have established; that is, which he intended to establish, and would, and did establish; meaning, more especially, the temple, and the holy of holies in it, which he directed Solomon to build, and was a settled dwelling place for him, 1 Kings 8:13, now all this may be considered as typical of the church of Christ, and of his bringing and planting his people there, which is a "mountain", and often signified by Mount Zion; is visible and immovable, the true members of it being interested in the love of God, on the sure foundation of electing grace, secured in the everlasting covenant, and built on the rock Christ Jesus; and is the Lord's "inheritance", chosen by him to be so, given to Christ, and possessed by him as such, and as dear to him, and more so, than a man's inheritance is to him: this is a "place" he has appointed, prepared, and made for himself to dwell in, and is the habitation of Father, Son, and Spirit; and is a "sanctuary" or holy place, consisting of holy persons established in Christ, as particular believers are, and the church in general is; and though now sometimes in an unsettled state as to outward things, yet ere long will be established on the top of the mountains: and hither the Lord brings his purchased people, as sheep into his fold, as children to his house, fitted up for them, as guests to partake of his entertainments; and this is an act of his powerful grace upon them, and of his distinguished goodness to them: and here he also plants them, for the church is a plantation, a garden, an orchard of pomegranates, with pleasant fruits; and such as are planted here are transplanted out of the world, and are first planted in Christ, and receive the ingrafted word; and though ministers may be instruments in planting, the Lord is the efficient; and those that are planted by him are choice pleasant plants, fruitful ones, and shall never be plucked up: but as this follows the passage of the Lord's people over Jordan into Canaan land, it may rather be considered as an emblem of the heavenly state, and of the Lord's bringing and planting his people there; which, like a mountain, is an immovable and unalterable state, an inheritance incorruptible and eternal, the dwellingplace of Jehovah, a sanctuary or holy place, which his hand prepared from the foundation of the world; and which he has established as everlasting habitations for his people, where he brings their souls at death, and both souls and bodies in the resurrection morn to dwell with him for ever; and which is a paradise, an Eden of pleasure, where he plants them as trees of righteousness, next to Christ the tree of life, and where they are always green, fruitful, flourishing, and shall never be hurt by any scorching heat or blasting wind, or be trodden under foot or plucked up.

"Thou wilt bring and plant them in the mountain of Thine inheritance, the place which Thou hast made for Thy dwelling-place, Jehovah, for the sanctuary, Lord, which Thy hands prepared." On the dagesh dirim. in מקּדשׁ, see Exodus 2:3. The futures are not to be taken as expressive of wishes, but as simple predictions, and are not to be twisted into preterites, as they have been by Knobel. The "mountain of Jehovah's inheritance" was not the hill country of Canaan (Deuteronomy 3:25), but the mountain which Jehovah had prepared for a sanctuary (Psalm 78:54), and chosen as a dwelling-place through the sacrifice of Isaac. The planting of Israel upon this mountain does not signify the introduction of the Israelites into the promised land, but the planting of the people of God in the house of the Lord (Psalm 92:14), in the future sanctuary, where Jehovah would perfect His fellowship with His people, and where the people would show themselves by their sacrifices to be the "people of possession," and would serve Him for ever as their King. This was the goal, to which the redemption from Egypt pointed, and to which the prophetic foresight of Moses raised both himself and his people in this song, as he beholds in spirit and ardently desires the kingdom of Jehovah in its ultimate completion.

(Note: Auberlen's remarks in the Jahrb.f. d. Theol. iii. p. 793, are quite to the point: "In spirit Moses already saw the people brought to Canaan, which Jehovah had described, in the promise given to the fathers and repeated to him, as His own dwelling-place where He would abide in the midst of His people in holy separation from the nations of the world. When the first stage had been so gloriously finished, he could already see the termination of the journey."..."The nation was so entirely devoted to Jehovah, that its own dwelling-place fell into the shade beside that of its God, and assumed the appearance of a sojourning around the sanctuary of Jehovah, for God went up before the people in the pillar of cloud and fire. The fact that a mountain is mentioned in Exodus 15:17 as the dwelling-place of Jehovah is no proof of a vaticinium post eventum, but is a true prophecy, having its natural side, however, in the fact that mountains were generally the sites chosen for divine worship and for temples; a fact with which Moses was already acquainted (Genesis 22:2; Exodus 3:1, Exodus 3:12; compare such passages as Numbers 22:41; Numbers 33:52; Micah 4:1-2). In the actual fulfilment its was Mount Zion upon which Jehovah was enthroned as King in the midst of his People.)

The song closes in Exodus 15:18 with an inspiring prospect of the time, when "Jehovah will be King (of His people) for ever and ever;" and in Exodus 15:19, it is dovetailed into the historical narrative by the repetition of the fact to which it owed its origin, and by the explanatory "for," which points back to the opening verse.

Thou shalt bring them in, and plant them in the mountain of thine {i} inheritance, in the place, O LORD, which thou hast made for thee to dwell in, in the Sanctuary, O Lord, which thy hands have established.

(i) Which was mount Zion, where later the temple was built.

15:17 Thou shalt bring them in - If he thus bring them out of Egypt, he will bring them into Canaan; for has he begun, and will he not make an end? Thou wilt plant them in the place which thou hast made for thee to dwell in - It is good dwelling where God dwells, in his church on earth, and in his church in heaven. In the mountains - In the mountainous country of Canaan: The sanctuary which thy hands have established - Will as surely establish as if it was done already.

15:1-21 This song is the most ancient we know of. It is a holy song, to the honour of God, to exalt his name, and celebrate his praise, and his only, not in the least to magnify any man. Holiness to the Lord is in every part of it. It may be considered as typical, and prophetical of the final destruction of the enemies of the church. Happy the people whose God is the Lord. They have work to do, temptations to grapple with, and afflictions to bear, and are weak in themselves; but his grace is their strength. They are often in sorrow, but in him they have comfort; he is their song. Sin, and death, and hell threaten them, but he is, and will be their salvation. The Lord is a God of almighty power, and woe to those that strive with their Maker! He is a God of matchless perfection; he is glorious in holiness; his holiness is his glory. His holiness appears in the hatred of sin, and his wrath against obstinate sinners. It appears in the deliverance of Israel, and his faithfulness to his own promise. He is fearful in praises; that which is matter of praise to the servants of God, is very dreadful to his enemies. He is doing wonders, things out of the common course of nature; wondrous to those in whose favour they are wrought, who are so unworthy, that they had no reason to expect them. There were wonders of power and wonders of grace; in both, God was to be humbly adored.
