For all who depend on the Law [seeking justification and salvation by obedience to the Law and the observance of rituals] are under a curse; for it is written, “Cursed (condemned to destruction) is everyone who does not abide by all things written in the book of the law, so as to practice them.”

Christ purchased our freedom and redeemed us from the curse of the Law and its condemnation by becoming a curse for us—for it is written, “Cursed is everyone who hangs [crucified] on a tree (cross)”—

For it is written that Abraham had two sons, one by the slave woman [Hagar] and one by the free woman [Sarah].

For it is written [in the Scriptures],

“Rejoice, o barren woman who has not given birth;
Break forth into a [joyful] shout, you who are not in labor;
For the desolate woman has many more children
Than she who has a husband.”
