Parallel
Galatians 4:30
Nestle 1904 Greek New Testament · Berean Standard Bible
Ἀλλὰ τί λέγει ἡ γραφή Ἔκβαλε τὴν παιδίσκην καὶ τὸν υἱὸν αὐτῆς οὐ γὰρ μὴ κληρονομήσει ὁ υἱὸς τῆς παιδίσκης μετὰ τοῦ υἱοῦ τῆς ἐλευθέρας
But what does the Scripture say? “Expel the slave woman and her son (note: Genesis 21:10), for the slave woman’s son will never share in the inheritance with the free woman’s son.”
