'Keep' in the Bible

In their case the prophecy of Isaiah is being fulfilled, which says,‘You will keep on hearing, but will not understand;You will keep on seeing, but will not perceive;

And He said to him, “Why are you asking Me about what is good? There is only One who is good; but if you wish to enter into life, keep the commandments.”

And He said, “Go into the city to a certain man, and say to him, ‘The Teacher says, “My time is near; I am to keep the Passover at your house with My disciples.”’”

Then He *said to them, “My soul is deeply grieved, to the point of death; remain here and keep watch with Me.”

And He *came to the disciples and *found them sleeping, and *said to Peter, “So, you men could not keep watch with Me for one hour?

Keep watching and praying that you may not enter into temptation; the spirit is willing, but the flesh is weak.”

And sitting down, they began to keep watch over Him there.

And if this should come to the governor’s ears, we will win him over and keep you out of trouble.”
