'It is Written' in the Bible

For all who rely on the works of the law are under a curse, because it is written: Everyone who does not continue doing everything written in the book of the law is cursed.

Christ has redeemed us from the curse of the law by becoming a curse for us, because it is written: Everyone who is hung on a tree is cursed.

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

For it is written:Rejoice, childless woman,who does not give birth.Burst into song and shout,you who are not in labor,for the children of the desolate are many,more numerous than thoseof the woman who has a husband.
