John Gill

Blessed is that servant whom his Lord, when he cometh,.... Whether in a way of judgment, as against Jerusalem; or at death, when he comes to remove him out of time, into eternity; or at the day of judgment, when he, the righteous judge, will give the crown of righteousness to him: shall find so doing; acting the faithful and wise part, ruling the household of God well; giving to all wholesome food, a proper portion of it, and that in the right time.
