17 Next another agent came out of the Temple [which is] resident within the atmosphere (or: within the midst of the heaven), he, too, having a sharp sickle.
18 Then another agent, having authority upon the Fire, came forth out of the altar and uttered (or: utters) a sound by a great outcry to the one continuously holding the sharp sickle, "You must send your sharp sickle and you must gather (pick) the clusters of the Land's (or: earth's) vineyard (grapevine), because her grapes are in their prime (are at the peak of ripeness)."
19 And so the agent cast (or: thrusts) his sickle into the Land (or: earth), and picks (gathers) the vineyard of the Land and he casts [it; them] into the great wine-press (trough; tub) of God's strong passion (rushing emotion; or: anger).
20 Then the wine-press (or: trough) was trodden (or: is trod as a path) outside of the City, and blood came (or: comes; goes) forth from out of the trough (or: wine-press) up to the horses' bridle – from a thousand six hundred stadia (a fixed standard of measure; a racecourse; a stadium).
