18 But it is good to be sought zealously in good at all times, and not only when I am present with you.
19 My children, for whom I am having birth pains again, until Christ is formed in you!
20 But I could wish to be present with you now, and to change my tone because I am perplexed about you.
21 Tell me, you who are wanting to be under the law, do you not understand the law?
22 For it is written that Abraham had two sons, one by the female slave and one by the free woman.
23 But the one by the female slave was born according to human descent, and the one by the free woman through the promise,
24 which things are spoken allegorically, for these women are two covenants, one from Mount Sinai, bearing children for slavery, who is Hagar.
