'Alert' in the Bible

Those slaves the master will find alert when he comes will be blessed. I assure you: He will get ready, have them recline at the table, then come and serve them.

If he comes in the middle of the night, or even near dawn, and finds them alert, those slaves are blessed.

But be alert at all times, praying that you may have strength to escape all these things that are going to take place and to stand before the Son of Man.”
