Verse 10. -
O house of Aaron, trust in the Lord. God's ministers were yet more bound than his people generally to trust in him.
He is their Help and their Shield (comp. ver. 9).
115:9-18 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 trust in him. Wherever there is right fear of God, there may be cheerful faith in him; those who reverence his word, may rely upon it. He is ever found faithful. The greatest need his blessing, and it shall not be denied to the meanest that fear him. God's blessing gives an increase, especially in spiritual blessings. And the Lord is to be praised: his goodness is large, for he has given the earth to the children of men for their use. The souls of the faithful, after they are delivered from the burdens of the flesh, are still praising him; but the dead body cannot praise God: death puts an end to our glorifying him in this world of trial and conflict. Others are dead, and an end is thereby put to their service, therefore we will seek to do the more for God. We will not only do it ourselves, but will engage others to do it; to praise him when we are gone. Lord, thou art the only object for faith and love. Help us to praise thee while living and when dying, that thy name may be the first and last upon our lips: and let the sweet savour of thy name refresh our souls for ever.
O house of Aaron, trust in the Lord,.... The family of the tribe of Levi, that was separated from the rest, to minister in the priest's office, to offer gifts and sacrifices for the people, and to bless them; and therefore ought to trust in the Lord, and set a good example to others: as ministers of the word should, who are intrusted with much by the Lord, and should trust in him for much; for every supply of gifts and grace; and the rather, as they are to be examples of faith to the people: and as all the saints under the Gospel dispensation are priests unto God, they should put their trust and confidence in the Lord; since their sacrifices cannot be acceptable and wellpleasing to God, without faith in him.
He is their help and their shield; the Lord is the help and shield of everyone of Aaron's family; of the priests under the law, and of ministers under the Gospel; and of all those who are kings and priests unto God; and therefore they should trust in him. This is repeated for the certainty of it, and for the particular application of it to Aaron's house.
