'Journey' in the Bible

and He instructed them that they should take nothing for their journey, except a mere staff—no bread, no bag, no money in their belt—

As He was setting out on a journey, a man ran up to Him and knelt before Him, and asked Him, “Good Teacher, what shall I do to inherit eternal life?”

And He began to speak to them in parables: “A man planted a vineyard and put a wall around it, and dug a vat under the wine press and built a tower, and rented it out to vine-growers and went on a journey.

It is like a man away on a journey, who upon leaving his house and putting his slaves in charge, assigning to each one his task, also commanded the doorkeeper to stay on the alert.
