23 However, the son by the handmaid was born according to the flesh, but the son by the free woman was born through promise.
23 The son of the slave woman was born by human connivance; the son of the free woman was born by God's promise.
23 The son of the slave wife was born in a human attempt to bring about the fulfillment of God's promise. But the son of the freeborn wife was born as God's own fulfillment of his promise.
