What did the seven thunders of Revelations say?

Answer 1

They were to be sealed up and not to be written at all - not even in the Bible.

(Rev 10:4) "And when the seven thunders had uttered their voices, I was about to write: and I heard a voice from heaven saying unto me, Seal up those things which the seven thunders uttered, and write them not." [King James Version]

(Rev 10:4) "After the thunder stopped, I was about to write what it had said. But a voice from heaven shouted, "Keep it secret! Don't write these things." [Contemporary English Version]

Answer 2

This might help. Revelation 10:3 And cried with a loud voice, as when a lion roareth: and when he had cried, seven thunders uttered their voices. Defender's Bible Notes Revelation 10:3 10:3 seven thunders. The “seven thunders” seem to correspond to the seven-times-manifested “voice of the Lord” in Psalm 29:3-9 (see notes thereon). This psalm is clearly describing retroactively the events of the great Flood in the days of Noah (“flood” in Psalm 29:10 is the Hebrew mabbul, a word used only for the Noahic cataclysm). At the first “voice of the Lord” (Psalm 29:3), the psalmist saw in his vision that “the God of glory thundereth: the LORD is upon many waters.” This great cataclysm marked the first time in history that the rebels on earth had ever heard thunder, for before that, “the LORD God had not caused it to rain upon the earth” (Genesis 2:5). The seven thunderous voices at the Flood had been voices of judgment, and the inference here in Revelation is the same. Yet the Lord told John not to record what they said, implying that there would still be time for human repentance before the final destruction would come. Just as the earth’s rainbow had signified God’s mercy in Noah’s day, so His rainbow crown will indicate that God’s mercy and long-suffering have not yet been fully exhausted. Note also Daniel 12:4,7,9.
