3:16 Now the promises were spoken to Abraham and to his descendant. 1 Scripture 2 does not say, “and to the descendants,” 3 referring to many, but “and to your descendant,” 4 referring to one, who is Christ.
3:20 Now an intermediary is not for one party alone, but God is one. 5
1 tn Grk “his seed,” a figurative extension of the meaning of σπέρμα (sperma) to refer to descendants (L&N 10.29).
2 tn Grk “It”; the referent (the scripture) has been specified in the translation for clarity. The understood subject of the verb λέγει (legei) could also be “He” (referring to God) as the one who spoke the promise to Abraham.
3 tn Grk “to seeds.” See the note on “descendant” earlier in this verse. Here the term is plural; the use of the singular in the OT text cited later in this verse is crucial to Paul’s argument.
4 tn See the note on “descendant” earlier in this verse.
sn A quotation from Gen 12:7; 13:15; 17:7; 24:7.
5 tn The meaning of this verse is disputed. According to BDAG 634 s.v. μεσίτης, “It prob. means that the activity of an intermediary implies the existence of more than one party, and hence may be unsatisfactory because it must result in a compromise. The presence of an intermediary would prevent attainment, without any impediment, of the purpose of the εἶς θεός in giving the law.” See also A. Oepke, TDNT 4:598-624, esp. 618-19.
