Revelation 10:2-3

He had a little book open in his hand;.  And he set his right foot on the sea and his left foot on the land, and cried with a loud voice, as when a lion roars.  When he cried out, seven thunders uttered their voices.

·        His awful voice was echoed by seven thunders, seven solemn and terrible ways of discovering the mind of God (MH)

·        “The contents of the little book are nowhere revealed in Revelation, but they seem to represent in this vision the written authority given to the angel to fulfill his mission.” (Walvoord)

Ezekiel 2:9  Now when I looked, there was a hand stretched out to me; and behold, a scroll of a book was in it.

Jeremiah 25:30  Therefore prophesy against them all these words, and say to them:  “The LORD will roar from on high, and utter His voice from His holy habitation; He will roar mightily against His fold.  He will give a shout, as those who tread the grapes, against all the inhabitants of the earth.
