Psalms 115:9

In these verses, I. We are earnestly exhorted, all of us, to repose our confidence in God, and not suffer our confidence in him to be shaken by the heathens' insulting over us upon the account of our present distresses. It is folly to trust in dead images, but it is wisdom to trust in the living God, for he is a help and a shield to those that do trust in them, a help to furnish them with and forward them in that which is good, and a shield to fortify them against and protect them from every thing that is evil. Therefore, 1. Let Israel trust in the Lord; the body of the people, as to their public interests, and every particular Israelite, as to his own private concerns, let them leave it to God to dispose of all for them, and believe it will dispose of all for the best and will be their help and shield. 2. Let the priests, the Lord's ministers, and all the families of the house of Aaron, trust in the Lord, (Psa 115:10); they are most maligned and struck at by the enemies and therefore of them God takes particular care. They ought to be examples to others of a cheerful confidence in God, and a faithful adherence to him in the worst of times. 3.
