72:2-17 This is a prophecy of the kingdom of Christ; many passages in it cannot be applied to the reign of Solomon. There were righteousness and peace at first in the administration of his government; but, before the end of his reign, there were troubles and unrighteousness. The kingdom here spoken of is to last as long as the sun, but Solomon's was soon at an end. Even the Jewish expositors understood it of the kingdom of the Messiah. Observe many great and precious promises here made, which were to have full accomplishment only in the kingdom of Christ. As far as his kingdom is set up, discord and contentions cease, in families, churches, and nations. The law of Christ, written in the heart, disposes men to be honest and just, and to render to all their due; it likewise disposes men to live in love, and so produces abundance of peace. Holiness and love shall be lasting in Christ's kingdom. Through all the changes of the world, and all the changes of life, Christ's kingdom will support itself. And he shall, by the graces and comforts of his Spirit, come down like rain upon the mown grass; not on that cut down, but that which is left growing, that it may spring again. His gospel has been, or shall be, preached to all nations. Though he needs not the services of any, yet he must be served with the best. Those that have the wealth of this world, must serve Christ with it, do good with it. Prayer shall be made through him, or for his sake; whatever we ask of the Father, should be in his name. Praises shall be offered to him: we are under the highest obligations to him. Christ only shall be feared throughout all generations. To the end of time, and to eternity, his name shall be praised. All nations shall call HIM blessed.
16. The spiritual blessings, as often in Scripture, are set forth by material, the abundance of which is described by a figure, in which a "handful" (or literally, "a piece," or small portion) of corn in the most unpropitious locality, shall produce a crop, waving in the wind in its luxuriant growth, like the forests of Lebanon.
they of the city … earth—This clause denotes the rapid and abundant increase of population—
the city—Jerusalem, the center and seat of the typical kingdom.
flourish—or, glitter as new grass—that is, bloom. This increase corresponds with the increased productiveness. So, as the gospel blessings are diffused, there shall arise increasing recipients of them, out of the Church in which Christ resides as head.
