'Watch' in the Bible

for it is written and forever remains written,‘He will command His angels concerning You to guard and protect You,’

Whether he comes in the second watch (before midnight), or even in the third (after midnight), and finds them so [prepared and ready], blessed are those servants.

But keep alert at all times [be attentive and ready], praying that you may have the strength and ability [to be found worthy and] to escape all these things that are going to take place, and to stand in the presence of the Son of Man [at His coming].”
