'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 sure of this, that if the head of the house had known at what time the thief was coming, he [would have been awake and alert, and] would not have allowed his house to be broken into.

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.”
