'It is Written' in the Bible

For as many as are out of works of the Law, these are under a curse; for it is written, "Cursed is everyone who does not continue in all things which are written in the Book of the Law, to do them."

Christ redeemed us from the curse of the Law, being made a curse for us (for it is written, "Cursed is everyone having been hanged on a tree");

For it is written: Abraham had two sons, the one out of the slave-woman, and one out of the free woman.

For it is written, "Rejoice, barren one not bearing; break forth and shout, you not travailing; for more are the children of the desolate than she having the husband."
