Parallel
Galatians 4:30
Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Ἀλλὰ τί λέγει ἡ γραφή; Ἔκβαλε τὴν παιδίσκην καὶ τὸν υἱὸν αὐτῆς, οὐ γὰρ μὴ κληρονομήσῃ 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.”
