Observe, 1. Those that are of a slothful disposition, that love their ease and cannot apply their minds to any business, are not fit to be employed, no, not so much as to be sent on an errand, for they will neither deliver a message with any care nor make any haste back. Such therefore are very unmeet to be ministers, Christ's messengers; he will not own the sending forth of sluggards into his harvest. 2. Those that are guilty of so great an oversight as to entrust such with any affair, and put confidence in them, will certainly have vexation with them. A slothful servant is to his master as uneasy and troublesome as vinegar to the teeth and smoke to the eyes; he provokes his passion, as vinegar sets the teeth on edge, and occasions him grief to see his business neglected and undone, as smoke sets the eyes a weeping.
