'Alert' in the Bible

Watch! Be alert! For you don’t know when the time is coming.

It is like a man on a journey, who left his house, gave authority to his slaves, gave each one his work, and commanded the doorkeeper to be alert.

Therefore be alert, since you don’t know when the master of the house is coming—whether in the evening or at midnight or at the crowing of the rooster or early in the morning.

And what I say to you, I say to everyone: Be alert!”

He said to them, "My soul is deeply grieved, even to the point of death. Remain here and stay alert."
