'Keep' in the Bible

He was also saying to them, “You are experts at setting aside the commandment of God in order to keep your tradition.

“Take heed, keep on the alert; for you do not know when the appointed time will come.

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

And He *came and *found them sleeping, and *said to Peter, “Simon, are you asleep? Could you not keep watch for one hour?

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