ISB ~ Luke 1 v33
the house of Jacob:i.e., the kingdom of Israel.
• Since the eighth century B.C., the northern tribes of Israel had been scattered among the Gentiles (2 Kings 17:2123), and since the sixth century B.C., many from the southern tribes of Judah and Benjamin had likewise lived in exile throughout the ancient world (2 Kings 25:8-11). The prophets lamented this tribal disintegration of God’s people but announced a future reunion of Jacob’s descendants under the Davidic Messiah (Is 11:12; Ezek 37:15-24; Hos 1:10-11; Amos 9:9-12). Jesus, says Gabriel, is this anointed Davidic ruler who will re-gather the tribes of Israel,
together with allnations, into his glorious kingdom (Mt 28:18-20; Acts 15:15-18; Rom 11:2527) (CCC 709-10). See note on Lk 4:43.
