'Open' in the Bible

“And to the angel (divine messenger) of the church in Philadelphia write:“These are the words of the Holy One, the True One, He who has the key [to the house] of David, He who opens and no one will [be able to] shut, and He who shuts and no one opens:

‘I know your deeds. See, I have set before you an open door which no one is able to shut, for you have a little power, and have kept My word, and have not renounced or denied My name.

After this I looked, and behold, a door standing open in heaven! And the first voice which I had heard, like the sound of a [war] trumpet speaking with me, said, “Come up here, and I will show you what must take place after these things.”

I saw in the right hand of Him who was seated on the throne a scroll written on the inside and on the back, closed and sealed with seven seals.

And I saw a strong angel announcing with a loud voice, “Who is worthy [having the authority and virtue] to open the scroll and to break its seals?”

And no one in heaven or on earth or under the earth [in Hades, the realm of the dead] was able to open the scroll or look into it.

And I began to weep greatly because no one was found worthy to open the scroll or look into it.

Then one of the [twenty-four] elders said to me, “Stop weeping! Look closely, the Lion of the tribe of Judah, the Root of David, has overcome and conquered! He can open the scroll and [break] its seven seals.”

Then I saw as the Lamb (Christ) broke one of the seven seals [of the scroll initiating the judgments], and I heard one of the four living creatures call out as with a voice of thunder, “Come.”

When He (the Lamb) broke open the third seal, I heard the third living creature call out, “Come.” I looked, and behold, a black horse [of famine]; and the rider had in his hand a pair of scales (a balance).

When He (the Lamb) broke open the fourth seal, I heard the voice of the fourth living creature call out, “Come.”

When He (the Lamb) broke open the fifth seal, I saw underneath the altar the souls of those who had been slaughtered because of the word of God, and because of the testimony which they had maintained [out of loyalty to Christ].

I looked when He (the Lamb) broke open the sixth seal, and there was a great earthquake; and the sun became black as sackcloth [made] of hair, and the whole moon became like blood;

When He (the Lamb) broke open the seventh seal, there was silence in heaven for about half an hour [in awe of God’s impending judgment].

and he had a little book (scroll) open in his hand. He set his right foot on the sea and his left foot on the land;

Then the voice which I heard from heaven, I heard again speaking to me, and saying, “Go, take the book (scroll) which is open in the hand of the angel who is standing on the sea and on the land.”

And their dead bodies will lie exposed in the open street of the great city (Jerusalem), which in a spiritual sense is called [by the symbolic and allegorical names of] Sodom and Egypt, where also their Lord was crucified.

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.

After these things I looked, and the temple (sanctuary) of the tabernacle of the testimony in heaven was opened,
