Galatians 4:30
Patriarchal Greek New Testament (1904) · Berean Standard Bible
ἀλλὰ τί λέγει ἡ γραφή; ἔκβαλε τὴν παιδίσκην καὶ τὸν υἱὸν αὐτῆς· οὐ μὴ γὰρ 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.”
