But what does the Scripture say? Send away the slave-woman and her son; for the slave's son shall not be heir along with the son of the free woman.

And because you are sons, God sent forth the spirit of his Son into your hearts, crying, "Dear, dear Father!"

So each one of you is no longer a slave, but a son, and if a son, then an heir, too, through God's grace.

but while the son by the slave woman was born according to the flesh, the son by the free woman was born in fulfilment of a promise.

but just as in old times the son born by the flesh used to persecute the son born by the power of the Spirit, so also it is now.
