Cyrill of Alexandria
Those who are bound by a spirit of servitude, along with the offspring of the earthly Jerusalem, will ultimately give way in honor to the children of the free woman, who is our spiritual mother, justified through Christ, and called into a state of freedom by the liberty of the Spirit, as noted in Romans 8:15 and Galatians 4:25-26. Consider, if you will, the clarity of this argument: the first to present an offering is the tribe of Judah, from which Christ was physically descended; and following him are Issachar and Zebulun, both of whom are free and represent the free.
