'Seen' in the Bible

I counsel you to buy from Me gold that has been heated red hot and refined by fire so that you may become truly rich; and white clothes [representing righteousness] to clothe yourself so that the shame of your nakedness will not be seen; and healing salve to put on your eyes so that you may see.

Then the angel whom I had seen standing on the sea and the land raised his right hand [to swear an oath] to heaven,

And the temple of God which is in heaven was opened; and the ark of His covenant appeared in His temple, and there were flashes of lightning, loud rumblings and peals of thunder and an earthquake and a great hailstorm.

Then another sign [of warning] was seen in heaven: behold, a great fiery red dragon (Satan) with seven heads and ten horns, and on his heads were seven royal crowns (diadems).

(“Behold, I am coming like a thief. Blessed is he who stays awake and who keeps his clothes [that is, stays spiritually ready for the Lord’s return], so that he will not be naked—spiritually unprepared—and men will not see his shame.”)
