28 Now you,¹ brothers, like Isaac, are ⁿchildren of promise. 29 But just as at that time ^ohe who was born according to the flesh ^ppersecuted him who was born according to the Spirit, ^qso also it is now. 30 But what does the Scripture say? ^r“Cast out the slave woman and her son, for the son of the slave woman shall not inherit with the son of the free woman.” 31 So, brothers, we are not children of the slave but ^sof the free woman.
