John Mark
Mark 13:34ESV·traditional attribution

It is like a man going on a journey, when he leaves home and puts his servants in charge, each with his work, and commands the doorkeeper to stay awake.

We have here the application of this prophetical sermon; now learn to look forward in a right manner. I. "As to the destruction of Jerusalem, expect it to come very shortly; as when the branch of the fig-tree becomes soft, and the leaves sprout forth, ye expect that summer will come shortly, Mar 13:28. When second causes begin to work, ye expect their effects in their proper order and time.

John Gill Reformed Baptist @doctorgill

Lest coming suddenly,.... Unthought of, and unexpected, at an unawares: he find you sleeping; inactive in the exercise of grace, and negligent in the performance of duty; unprepared for his coming, and unfit for service.

Albert Barnes Presbyterian @notesbybarnes

Verse 34. Who left his house. The word house often means family. Our Saviour here represents himself as going away, leaving his household the Church, assigning to the apostles and all his servants their duty, and leaving it uncertain when he would return.
