Old Testament prophecy in Jesus Birth
The possibility of understanding “seed” (“offspring,” NIV) as either singular or plural (cf. Ps 89:4, 29, 36, where the Heb. word for “seed” is translated “line” in connection with the Davidic covenant) is exploited by Paul in Galatians 3:16: “The promises were spoken to Abraham and to his seed. The Scripture [Gen 12:7; 13:15; 24:7] does not say ‘and to seeds,’ meaning many people, but ‘and to your seed,’ meaning one person, who is Christ” (cf. also “the Seed” [= Christ] in Gal 3:19 and “Abraham’s seed” [= Christians] in Gal 3:29). The trajectory from the Abrahamic covenant through the Davidic covenant to the new covenant in Christ is strengthened by the repetition of words such as “seed” used in a messianic sense (cf. similarly John M.G. Barclay, Obeying the Truth: A Study of Paul’s Ethics in Galatians [Edinburgh: T. and T. Clark, 1988], p. 89; cf. also John 7:42 and NIV mg. there; Acts 13:23 [“descendants”]; cf. further Dale Goldsmith, “Acts 13 33–37: A Pesher on 2 Samuel 7,” JBL 87, 3 [1968]: 321–24).
