ISB ~ Matthew 19 v28

the new world:The Greek could be rendered “re-generation” as in Tit 3:5. The historian Josephus uses this expression with reference to Israel’s “restoration” after the Exile. This latter connotation is closest to Jesus’ meaning here, where the establishment of the universal Church includes the reestablishment of Israel under the leadership of the Twelve. on twelve thrones: Jesus portrays the Church as the restored kingdom of Israel (cf. Rev 7:4-8). As the royal son of David (1:1), he reconstitutes the Davidic empire that governed the 12 tribes (2 Sam 5:1-5) along with other nations (2 Sam 8:1-15; 1 Kings 4:2021). He thus appoints the apostles to his royal cabinet and invests them with authority to minister and judge in the new kingdom (Lk 22:28-30).

• Jesus’ language recalls Ps 122:3-5. In context, Jerusalem is the city where the thrones of the Davidic kingdom stood and where Israel’s tribes went to find justice. In the New Covenant, Christ imparts justice through his apostles in the liturgy of the heavenly Jerusalem (cf. Heb 12:22-24; Rev 21:1-14; CCC 551, 765). See notes on Mt 5:14 and 10:2.
