Galatians:4:28-31
rsv@Galatians:4:28 @ Now we, brethren, like Isaac, are children of promise.
rsv@Galatians:4:29 @ But as at that time he who was born according to the flesh persecuted him who was born according to the Spirit, so it is now.
rsv@Galatians:4:30 @ But what does the scripture say? "Cast out the slave and her son; for the son of the slave shall not inherit with the son of the free woman."
rsv@Galatians:4:31 @ So, brethren, we are not children of the slave but of the free woman.
