Galatians 4:29

29 But just as at that time the child who was born according to the flesh persecuted the child who was born according to the Spirit, so it is now also.

Galatians 4:29 In-Context

27 For it is written, "Rejoice, you childless one, you who bear no children, burst into song and shout, you who endure no birth pangs; for the children of the desolate woman are more numerous than the children of the one who is married."
28 Now you, my friends, are children of the promise, like Isaac.
29 But just as at that time the child who was born according to the flesh persecuted the child who was born according to the Spirit, so it is now also.
30 But what does the scripture say? "Drive out the slave and her child; for the child of the slave will not share the inheritance with the child of the free woman."
31 So then, friends, we are children, not of the slave but of the free woman.
