IV. Upon the whole matter, they are cautioned against inordinate fear and grief, for in these precious promises there is enough to silence both. 1. They must not tremble as those that have no hope in the apprehension of future further trouble that might threaten them (v. 10): Fear thou not, O my servant Jacob! neither be dismayed. Note, Those that are God's servants must not give way to disquieting fears, whatever difficulties and dangers may be before them. 2. They must not sorrow as those that have no hope for the troubles which at present they lie under, v. 15. "Why criest thou for thy affliction? It is true thy carnal confidences fail thee, creatures are physicians of no value, but I will heal thy wound, and therefore, Why criest thou? Why dost thou fret and complain thus? It is for thy sin (v. 14, 15), and therefore, instead of repining, thou shouldest be repenting. Wherefore should a man complain for the punishment of his sins? The issue will be good at last, and therefore rejoice in hope."
