Isaiah 63:1

Who — The church makes enquiry, and that with admiration, who it is that appears in such a habit or posture? Edom — Idumea, where Esau dwelt. It is put for all the enemies of the church. Bozrah — The capital city of Idumea. Here is also an allusion to the garments of this conqueror, Edom signifying red, and Bozrah a vintage. Glorious — Such as generals march before their armies in. Righteousness — Here Christ gives an answer, wherein he both asserts his fidelity, that he will faithfully perform what he hath promised, and that he will truly execute justice. Mighty — I have power to accomplish salvation.
