Translation
The voice I had heard from heaven was speaking to me again, saying, “Go, take the little scroll which has been opened
and is in the hand of the angel who is standing upon the sea and the land.”
Paraphrase
The voice I had heard from heaven was speaking to me again, saying,
“go, take the short message
that is not sealed but is under the control of one who can do anything he wants with this short message, i.e. the messenger who has authority over the unknown and the familiar.”
