Luke 9:29

9:29 As98 he was praying,99 the appearance of his face was transformed,100 and his clothes became very bright, a brilliant white.101

98	tn Grk “And as.” Here καί (kai) has not been translated because of differences between Greek and English style.
99	tn Here the preposition ἐν (en) plus the dative articular aorist infinitive has been translated as a temporal clause (ExSyn 595).
100	tn Or “the appearance of his face became different.” 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 the appearance of his face transformed, 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).
101	tn Or “became bright as a flash of lightning” (cf. BDAG 346 s.v. ἐξαστράπτω); or “became brilliant as light” (cf. BDAG 593 s.v. λευκός 1).
