'Speedy' in the Bible

These [two witnesses] have the power [from God] to shut up the sky, so that no rain will fall during the days of their prophesying [regarding judgment and salvation]; and they have power over the waters (seas, rivers) to turn them into blood, and to strike the earth with every [kind of] plague, as often as they wish.

and if anyone takes away from or distorts the words of the book of this prophecy, God will take away [from that one] his share from the tree of life and from the holy city (new Jerusalem), which are written in this book.
