² sn In 1st century Judaism and in the NT, there was the belief that the righteous get new, glorified bodies in order to enter heaven (1 Cor 15:42-49; 2 Cor 5:1-10). This transformation means the righteous will share the glory of God. One recalls the way Moses shared the Lord’s glory after his visit to the mountain in Exod 34. So the disciples saw Jesus transfigured, and they were getting a sneak preview of the great glory that Jesus would have (only his glory is more inherent to him as one who shares in the rule of the kingdom).
