If ekeinous be accepted here instead of autous, the
three disciples would be outside of the cloud. {Out of the cloud}
(ek t(8873) nephel(8873)). This voice was the voice of the Father like
that at the baptism of Jesus ( Lu 3:22  Mr 1:11  Mt 3:17 ) and
like that near the end ( Joh 12:28-30 ) when the people thought
it was a clap of thunder or an angel. {My son, my chosen} (Ho
huios mou, ho eklelegmenos). So the best documents (Aleph B L
Syriac Sinaitic). The others make it "My Beloved" as in  Mr 9:7  Mt 17:5 . These disciples are commanded to hear Jesus, God's Son,
even when he predicts his death, a pointed rebuke to Simon Peter
as to all.
