Revelation 4:1

JMNT(i) 1 After these things I saw (or: perceived) – and now consider this! – A door (or: gate; entrance; portal), having been opened (thus: standing open) within the atmosphere (or: heaven; sky). And the first sound (or: voice) which I hear (or: heard) [is; was] as a war-trumpet talking with me, saying, "Come up here (Ascend to this place), and I will proceed showing you what things it is necessary (binding) to birth (to come to be in existence) after these things."
