“Tell me, ye that desire to be under the law, do ye not hear the law?”
King James Version (KJV)
Matthew Henry's Concise Commentary
4:21-27 The difference between believers who rested in Christ only, and those who trusted in the law, is explained by the histories of Isaac and Ishmael. These things are an allegory, wherein, beside the literal and historical sense of the words, the Spirit of God points out something further. Hagar and Sarah were apt emblems of the two different dispensations of the covenant. The heavenly Jerusalem, the true church from above, represented by Sarah, is in a state of freedom, and is the mother of all believers, who are born of the Holy Spirit. They were by regeneration and true faith, made a part of the true seed of Abraham, according to the promise made to him.
“Then Eliashib the high priest rose up with his brethren the priests, and they builded the sheep gate; they sanctified it, and set up the doors of it; even unto the tower of Meah they sanctified it, unto the tower of Hananeel.”
