John Trapp on Isaiah 54:1

CHAP. LIV.

Ver. 1. SIng O barren, thou that didſt not bear] O Church Chriſtian, O Jeruſalem that art above, the mother of us all, the purchaſe of Chriſts paſſion, chap. 53. to whom thou haſt been a bloody ſpouſe, Acts 20.28. an Acheldama or field of blood, 1 Pet. 1.18, 19. he hath paid dear for thy fruitfulneſſe. As the blood of beaſts applied to the roots of trees maketh them ſprout and bear more fruit: ſo doth the blood of Chriſt, ſprinckled on the roots of mens hearts, make them more fruitful Chriſtians: as it did the Gentiles whoſe hearts were purified by Faith, Acts 15.9. See Gal. 4.27. The corn of wheat that fell into the ground and died there, abode not alone, but brought forth much fruit, Joh. 12.44.

For more are the children of the deſolate] The Chriſtian Church, made up of Jews and Gentiles, ſhall have a more numerous and glorious off-ſpring then ever the Synagogue had: Sarah ſhall have more iſſue then Hagar, Hannah then Peninnah.
