'Shut' 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.

These [two witnesses] have the power [from God] to shut up the sky, so that no rain will fall during the days of their prophesying [regarding judgment and salvation]; and they have power over the waters (seas, rivers) to turn them into blood, and to strike the earth with every [kind of] plague, as often as they wish.
