'Guarded' in the Bible

So give orders for the sepulchre to be securely guarded till the third day, for fear his disciples should come by night and steal the body, and then tell the people that he has come back to life; and so the last imposture will be more serious than the first."

Upon our arrival in Rome, Paul received permission to live by himself, guarded by a soldier.

I have gone through the glorious contest; I have run the race; I have guarded the faith.

I know your doings. I have put an opened door in front of you, which no one can shut; because you have but a little power, and yet you have guarded My word and have not disowned Me.

Because in spite of suffering you have guarded My word, I in turn will guard you from that hour of trial which is soon coming upon the whole world, to put to the test the inhabitants of the earth.
