Mark 13:34
It's like a man going away: he leaves his house and puts his servants in charge, each with their assigned task, and tells the one at the door to keep watch — the parable of the absent householder provides the framework for the disciples' situation. The householder has departed (Jesus, by his death and resurrection/ascension), left servants in charge (the disciples with the kingdom mission), each with their task (specific callings), and the doorkeeper must keep watch (the general vigilance of the whole community).
