Galatians 4:27

For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband.

For it is written,.... Isaiah 44:1, which is cited to prove, that the heavenly Jerusalem, or Gospel church state, is the mother of us all, and has brought forth, and still will bring forth, many souls to Christ, even many more than were under the legal dispensation by the Jewish church, though the Lord was an husband to them, Jeremiah 31:32. The words are,

rejoice thou barren that bearest not, break forth and cry thou that travailest not, for the desolate hath many more children than she which hath an husband; by her that was "barren", and "bore" not, and "travailed" not, and was "desolate", is not meant the Gentile world, which before the coming of Christ was barren and destitute of the knowledge of him, and from among whom very few were called by grace; but the Gospel church in the first beginnings of it, in Christ's time, and especially about the time of his death, and before the pouring forth of the Spirit on the day of Pentecost, when the number of its members were few; for the names of the disciples together were but 120, when it seemed to be barren, and desolate, and deprived of its husband Christ, but was quickly to have a large accession to, it, both of Jews and Gentiles; and therefore is called upon to "rejoice, break forth", and "cry"; that is, to break forth into songs of praise, and express her spiritual joy, by singing aloud, and setting forth in hymns and spiritual songs the glory of powerful and efficacious grace, in the conversion of such large numbers of souls, the like of which had never been known under the former administration. Three thousand were converted under one sermon, and added to this first Gospel church; and the number of its members still increased, and the number of the men that afterwards believed was about five thousand; and after this we hear of more believers being added to the Lord, both men and women; and also that a great company of the priests were obedient to the faith; and when out of this church, the apostles, and other preachers of the Gospel went everywhere into the Gentile world, thousands of souls were converted, and a large number of churches formed, and a spiritual seed has been preserved ever since; and in the latter day Zion will travail in birth, and bring forth a numerous offspring; a nation shall be born at once, and the fulness of the Gentiles shall be brought in. Agreeably to this sense the Jewish writers, Jarchi, Kimchi, and Aben Ezra, understand this passage of Jerusalem; as does also the Chaldee paraphrase, which renders it thus:

"Praise, O Jerusalem, which was as a barren woman that bringeth not forth; rejoice in praise, and be glad, who was as a woman which conceives not, for more are the children of Jerusalem forsaken than the children of the habitable city, saith the Lord.''
