31:22 How long wilt thou wander about, O thou backsliding daughter? for the LORD hath created {d} a new thing in the earth, A woman shall encompass a man.
(d) Because their deliverance from Babylon was a figure of their deliverance from sin, he shows how this would be procured that is, by Jesus Christ, whom a woman would conceive and bear in her womb. Which is a strange thing in earth, because he would be born of a virgin without man or he means that Jerusalem which was like a barren woman in her captivity would be fruitful as she that is joined in marriage and whom God blesses with children.
31:22 Backsliding - Running after idols; or seeking help from foreign nations, instead of applying to God. A woman - This seems to be a promise of the Jewish church in its time, and of the gospel - church, prevailing over all its enemies; though, considering the fewness of the church's members, with the multitude of its enemies, and their power, it seemed as strange a thing, as for a woman to prevail against a strong and mighty man.
31:21-26 The way from the bondage of sin to the liberty of God's children, is a high-way. It is plain, it is safe; yet none are likely to walk in it, unless they set their hearts towards it. They are encouraged by the promise of a new, unheard-of, extraordinary thing; a creation, a work of Almighty power; the human nature of Christ, formed and prepared by the power of the Holy Ghost: and this is here mentioned as an encouragement to the Jews to return to their own land. And a comfortable prospect is given them of a happy settlement there. Godliness and honesty God has joined: let no man think to put them asunder, or to make the one atone for the want of the other. In the love and favour of God the weary soul shall find rest, and the sorrowful shall find joy. And what can we see with more satisfaction than the good of Jerusalem, and peace upon Israel?
