The angel has a ‘“little book” open in verse 2.
Then the angel reads from the “little book” and SEVEN THUNDERS ARE ROARED OUT.
John is about to copy this down and is told NOT to write it down.
Then Yah from Heaven in vs 9 tells John to take the “little book” from the angel.
In vs 10, John takes the “little book” and eats it up — sweet as honey in his mouth but in his belly very bitter.
In vs 11 — why bitter? Because John must still yet prophesy again before many peoples, nations and tongues and kings. And how? John will do this as one of the Two Witnesses.
The “little book” John eats contains the 7 Thunders that are sealed. Thus, the 7 Thunders are WHAT the TWO WITNESSES WILL PREACH for 1260 days!!!!
