'It is Written' in the Bible

but a curse rests on those who have their root in the works of the Law; for it is written. Cursed is every one that continues not in all the things written in the Book of the Law, to do them.

Christ has redeemed us from the curse of the Law by becoming a curse for us (for it is written, Cursed is every one who is hanged upon a tree),

For it is written that Abraham had two sons, one by the slave woman and one by the free woman;

For it is written, Rejoice, O thou barren one who dost never bear, Break forth in joy, thou that dost not travail; For the children of the desolate woman are many. Yea, more than hers who has a husband.
