Galatians 3:8; Galatians 3:22; Galatians 4:30 (King James Version)

8 And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed . 22 But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe . 30 Nevertheless what saith the scripture? Cast out the bondwoman and her son: for the son of the bondwoman shall not be heir with the son of the freewoman.
