But the end of all things is at hand: be ye therefore sober, and watch unto prayer. (1 Peter 4:7)
But know this, that if the goodman of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up.
Continue in prayer, and watch in the same with thanksgiving. (Colossians 4:2)
And when Judah came toward the watch tower in the wilderness, they looked unto the multitude, and, behold, they were dead bodies fallen to the earth, and none escaped.
But watch thou in all things, endure afflictions, do the work of an evangelist, make full proof of thy ministry.
