Then the LORD's angel gave answer, and said, 'O LORD of Hosts, how long wilt thou be unmerciful to Jerusalem and to the cities of Judah, with whom thou hast been displeased now these seventy years?'

to the intent that now, unto the rulers and powers in heaven, might be known by the congregation the manifold wisdom of God,

Unto which prophets it was declared, that not unto themselves, but unto us, they should minister the things which are now showed unto you, of them which, by the holy ghost sent down from heaven, have preached unto you the things which the angels desire to behold.

Man

I lift up mine eyes, and looked: and behold, a man clothed in linen, whose loins were girded up with fine gold of Arabia:

Then came there six men out of the street of the upper port toward the north, and every man a weapon in his hand to the slaughter. There was one amongst them, that had on him a linen raiment, and a writer's inkhorn by his side. These went in, and stood beside the brazen altar:

and the seven angels came out of the temple, which had the seven plagues, clothed in pure and bright linen, and having their breasts girded with golden girdles.

And the warriors which were in heaven, followed him upon white horses, clothed with white and pure raynes:

Upon

And he had in his hand a little book open: and he put his right foot upon the sea, and his left foot on the earth.

How long

Upon this I heard one of the saints speaking, which saint said unto one that asked this question, "How long shall this vision of the daily sacrifice and of the wasting abomination endure: that the Sanctuary and the power shall so be trodden under foot?"

We see not our tokens. There is not one prophet more; no, not one is there among us, that understandeth any more.

and they cried with a loud voice saying, "How long tarriest thou Lord holy and true, to judge and to avenge our blood on them that dwell on the earth?"

General references

"When shall these things be? And what is the sign, when all these things shall be fulfilled?"
