'It is Written' in the Bible

For as many as are of the works of the law, are under the curse; for it is written, Cursed be every one that continueth not in all things which are written in the book of the law, to do them.

And that by the law no one is justified before God is evident; for it is written "The just shall live by faith:"

Christ hath redeemed us from the curse of the law, having been made a curse for us: for it is written, "Cursed is every one that hangeth on a tree:"

where it is written, that Abraham had two sons, one by a servant, and one by a free-woman?

For it is written, Rejoice thou barren, that for a while didst not bear, break forth and cry aloud for joy, thou that didst not travail with child; for many more are the children of the desolate than of her that hath an husband."
