Revelation 10:3

The seven thunders (ai epta brontai). A recognized group, but not explained here, perhaps John assuming them to be known. For brontai see already 1 Peter 4:5 ; 1 Peter 6:1 ; 1 Peter 8:5 . In Psalms 29:1 the Lord speaks in the sevenfold voice of the thunderstorm upon the sea. Their voices (ta eautwn pwna). Cognate accusative with elalhsan and eautwn (reflexive) means "their own." In John 12:28 the voice of the Father to Christ was thought by some to be thunder.
