Isaiah 54:2

With this prospect before her, even her dwelling-place would need enlarging. "Enlarge the space of thy tent, and let them stretch out the curtains of thy habitations; forbid not! lengthen thy cords, and fasten thy plugs." She is to widen out the space inside her tent, and they (יטּוּ has no definite subject, which is often the case where some subordinate servant is to be thought of) are to spread out far and wide the coverings of the framework of her dwelling, which is called mishkenōth (in the plural) on account of its roominess and magnificence: she is not to forbid it, thinking in her weakness of faith, "It is good enough as it is; it would be too large." The cords which hold up the walls, she is to lengthen; and the plugs, to which the cords are fastened, she is to ram fast into the earth: the former because the tent (i.e., the holy city, Jer 31:38-40, and the dwelling-place of the church generally, Isa 26:15) has to receive a large number of inhabitants; the latter because it will not be broken up so soon again (Isa 33:20).

The death of Christ is the life of the church and of all that truly belong to it; and therefore very fitly, after the prophet had foretold the sufferings of Christ, he foretels the flourishing of the church, which is a part of his glory, and that exaltation of him which was the reward of his humiliation: it was promised him that he should see his seed, and this chapter is an explication of that promise. It may easily be granted that it has a primary reference to the welfare and prosperity of the Jewish church after their return out of Babylon, which (as other things that happened to them) was typical of the glorious liberty of the children of God, which through Christ we are brought into; yet it cannot be denied but that it has a further and principal reference to the gospel church, into which the Gentiles were to be admitted. And the first words being understood by the apostle Paul of the New Testament Jerusalem (Gal 4:26) may serve as a key to the whole chapter and that which follows. It is here promised concerning the Christian church, I. That, though the beginnings of it were small, it should be greatly enlarged by the accession of many to it among the Gentiles, who had been wholly destitute of church privileges (Isa 54:1-5). II. That though sometimes God might seem to withdraw from her, and suspend the tokens of his favour, he would return in mercy and would not return to contend with them any more (Isa 54:6-10). III. That, though for a while she was in sorrow and under oppression, she should at length be advanced to greater honour and splendour than ever (Isa 54:11, Isa 54:12). IV. That knowledge, righteousness, and peace, should flourish and prevail (Isa 54:13, Isa 54:14). V. That all attempts against the church should be baffled, and she should be secured from t…
