2. Plenty, v. 18. This is put first, because it is the reverse of the judgment threatened in the foregoing chapters. (1.) The streams of this plenty overflow the land and enrich it: The mountains shall drop new wine and the hills shall flow with milk, such great abundance shall they have of suitable provision, both for babes and for strong men. It intimates the abundance of vineyards, and all fruitful; and the abundance of cattle in the pastures that fill them with milk. And, to make the corn-land fruitful, the rivers of Judah shall flow with water, so that the country shall be like the garden of Eden, well-watered every where and greatly enriched, Ps. lxv. 9. But this seems to be meant spiritually; the graces and comforts of the new covenant are compared to wine and milk (Isa. lv. 1), and the Spirit to rivers of living water, John vii. 38. And these gifts abound much more under the New Testament than they did under the Old; when believers receive grace for grace from Christ's fulness, when they are enriched with everlasting consolations, and filled with joy and peace in believing, then the mountains drop new wine, and the hills flow with milk. Drink you, drink abundantly, O beloved! When there is plentiful effusion of the Spirit of grace, then the rivers of Judah flow with water, and make glad, not only the city of our God (Ps. xlvi. 4), but the whole land. (2.) The fountain of this plenty is in the house of God, whence the streams take their rise, as those waters of the sanctuary (Ezek. xlvii. 1) from under the threshold of the house, and the river of life out of the throne of God and the Lamb, Rev. xxii. 1. The psalmist, speaking of Zion, says, All my springs are in thee, Ps. lxxxvii. 7. Those that take temporal blessings to be meant in the former part of the verse, yet by this fountain out of the house of the Lord understand the grace of God, which, if we abound in temporal blessings, we have so much more need of, that we may not abuse them. Christ himself is the fountain; his merit and grace cleanse us, refresh us, and make us fruitful. This is said to water the valley of Shittim, which lay a great way off from the temple at Jerusalem, on the other side of Jordan, and was a dry and barren valley, which intimates that gospel-grace, flowing from Christ, shall reach far, even to the Gentile world, to the most remote regions of it, and shall make those to abound in the fruits of righteousness who had long lain as the barren wilderness. This grace is a fountain overflowing, ever-flowing, from which we may be continually drawing, and yet need not fear its being drawn dry. This fountain comes out of the house of the Lord above, from his temple in heaven, flows all that good which here we are daily tasting the streams of, but hope to be shortly, hope to be eternally, drinking at the fountain-head of.
