'It is Written' in the Bible

For all who seek to be right with God by trying to meet all the requirements of the law of Moses are under a curse [from God], because it is written [Deut. 27:26], "Every person is cursed [i.e., cut off from God] who does not continue to obey all of the requirements written in the law of Moses."

Christ bought us back from the curse [caused by our not obeying all the requirements] of the law of Moses; He became a curse for us [by dying on the cross], for it is written [Deut. 21:23], "Every one who hangs on a tree [i.e., a cross] is cursed [i.e., cut off from God]."

For it is written in the law about Abraham's two sons [Gen. 16]; one [was] by his slave woman [Hagar] and the other by the free woman, [his wife, Sarah].

For it is written [Isa. 40:1], "[Woman] you should be happy that you have not had children. Cry over your inability to experience the pain of childbirth. For the deserted woman has had more children than the one with a husband."
