'Keep' in the Bible

I have known thy works; lo, I have set before thee a door -- opened, and no one is able to shut it, because thou hast a little power, and didst keep my word, and didst not deny my name;

'Because thou didst keep the word of my endurance, I also will keep thee from the hour of the trial that is about to come upon all the world, to try those dwelling upon the earth.
