Galatians 4:28-31
28 And we, [believing] brothers and sisters, like Isaac, are children [not merely of physical descent, like Ishmael, but are children born] of promise [born miraculously].
29 But as at that time the child [of ordinary birth] born according to the flesh persecuted the son who was born according to [the promise and working of] the Spirit, so it is now also.(A)
30 But what does the Scripture say?
“Cast out the bondwoman [Hagar] and her son [Ishmael],
For never shall the son of the bondwoman be heir and share the inheritance with the son of the free woman.”(B)
For never shall the son of the bondwoman be heir and share the inheritance with the son of the free woman.”(B)
