3 For thou shalt break forth on the right hand and on the left; and thy seed shall inherit the Gentiles, and make the desolate cities to be inhabited.
3 For you will spread out to the right and to the left; your descendants will dispossess nations and settle in their desolate cities.
3 For you will spread abroad to the right and to the left, and your offspring will possess the nations and will people the desolate cities.
3 You're going to need lots of elbow room for your growing family. You're going to take over whole nations; you're going to resettle abandoned cities.
3 For you shall expand to the right and to the left, And your descendants will inherit the nations, And make the desolate cities inhabited.
3 For you will soon be bursting at the seams. Your descendants will occupy other nations and resettle the ruined cities.
Matthew Henry's Commentary on Isaiah 54:3
Commentary on Isaiah 54:1-5
(Read Isaiah 54:1-5)
Observe the low state of religion in the world, for a long time before Christianity was brought in. But by preaching the gospel, multitudes were converted from idols to the living God. This is matter of great rejoicing to the church. The bounds of the church were extended. Though its state on earth is but mean and movable, like a tent or tabernacle, it is sometimes a growing state, and must be enlarged as the family increases. But the more numerous the church grows, the more she must fortify herself against errors and corruptions. Thy Maker is thy Husband. Christ is the Holy One of Israel, the Mediator of the covenant made with the Old Testament church. Long he had been called the God of Israel; but now he shall be called the God of the whole earth. And he will cleanse from sin, and cause every true believer to rejoice in this sacred union. We never can enough admire this mercy, or duly value this privilege.
