'Birth' in the Bible

But when the one who set me apart from birth and called me by his grace was pleased

We who are Jews by birth and not “Gentile sinners”

My little children, of whom I travail in birth again until Christ be formed in you,

But the child of the slave woman was born according to the flesh and had an ordinary birth, while the son of the free woman was born in fulfillment of the promise.

Which things have a secret sense; because these women are the two agreements; one from the mountain of Sinai, giving birth to servants, which is Hagar.

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.

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.

For neither is circumcision anything [of any importance], nor uncircumcision, but [only] a new creation [which is the result of a new birth—a spiritual transformation—a new nature in Christ Jesus].
