'Able' in the Bible

And I saw a strong angel saying in a loud voice, Who is able to make the book open, and to undo its stamps?

And no one in heaven, or on the earth, or under the earth, was able to get the book open, or to see what was in it.

And I was very sad, because there was no one able to get the book open or to see what was in it.

And they gave worship to the dragon, because he gave authority to the beast; and worshipping the beast, they said, Who is like the beast? and who is able to go to war with him?

So that no man might be able to do trade but he who has the mark, even the name of the beast or the number of his name.

And the house of God was full of smoke from the glory of God, and from his power, and no one was able to go into the house of God, till the seven punishments of the seven angels were ended.
