28 Now you,¹ brothers, ^mlike Isaac, ⁿare children of promise. 29 But just as at that time he who was born according to the flesh ^opersecuted him who was born according to the Spirit, ^pso also it is now. 30 But what does the Scripture say? ^q“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 ^rof the free woman.
