Galatians 4:22-23
Context4:22 For it is written that Abraham had two sons, one by the 3 slave woman and the other by the free woman. 4:23 But one, the son by the slave woman, was born by natural descent, 4 while the other, the son by the free woman, was born through the promise.
1 tn Grk “brothers.” See note on the phrase “brothers and sisters” in 1:11.
2 sn A quotation from Gen 21:10. The phrase of the free woman does not occur in Gen 21:10.
3 tn Paul’s use of the Greek article here and before the phrase “free woman” presumes that both these characters are well known to the recipients of his letter. This verse is given as an example of the category called “well-known (‘celebrity’ or ‘familiar’) article” by ExSyn 225.
4 tn Grk “born according to the flesh”; BDAG 916 s.v. σάρξ 4 has “Of natural descent τὰ τέκνα τῆς σαρκός children by natural descent Ro 9:8 (opp. τὰ τέκνα τῆς ἐπαγγελίας). ὁ μὲν ἐκ τῆς παιδίσκης κατὰ σάρκα γεγέννηται Gal 4:23; cp. vs. 29.”
