(9) O Israel.--There is consummate art in this sudden change of address. It is like the pointed application of some general truth in a sermon. It is possible that in the liturgic use a change in the music was made here, the Levites and choir turning to the people with a loud burst of song.

He is their help and their shield.--The original form of this motto of trust appears in Psalm 33:20. Here the change of person suggests some musical arrangement. Apparently one part of the choir, or, it may be, one officiating priest, addressed successively the whole congregation with the charge, "trust in Jehovah," and each time the full choir took up the refrain, "He is their helper and shield," repeating to the priest the ground on which he urged confidence and loyalty. Then in Psalm 115:12-13 congregation and choir join, changing to the first person.

Verses 9-11. - The idols and the idol-worshippers having been sufficiently scorned; the latter especially, for their "trust" in idols, Israel is exhorted to trust in the only sure Object of confidence, Jehovah. Three several times the leader of the choir gives forth the call - " Trust in the Lord " - and three several times the choir responds with the acknowledgment that he, and he alone, "is their Help and Shield." The exhortation seems to be addressed, first, to the lay people generally (ver. 9); then to the clerical order (ver. 10); finally, to all, whether laity or clergy, who are true Israelites at heart (comp. vers. 12, 13). Verse 9. - O Israel, trust thou in the Lord. Follow not the example of the heathen who trust in idols. Rather, be an example to them. He is their Help and their Shield (comp. Psalm 33:20). The change of per son implies a change of speaker.

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 Israel, trust thou in the Lord,.... Or, "the house of Israel hath trusted in the Lord": so the Septuagint, Vulgate Latin, Syriac, Arabic, and Ethiopic versions: the Targum is,

"Israel trusteth in the Word of the Lord;''

in distinction from the Heathens, that trust in their idols. But it is better rendered as an imperative, trust thou; it being an exhortation to Israel to trust in the Lord, in opposition to idols; and may be understood of Israel, literally taken, who were God's chosen covenant people, to whom he had made a revelation of himself, and of his will; and therefore should trust in him, and in no other; and of spiritual Israel, or all the elect of God, and redeemed of the Lamb; every Israelite indeed; every wrestling Jacob, and prevailing Israel; every praying soul; every sensible sinner, Jew or Gentile. It becomes them to trust in the Lord, not in the creature; not in their own strength, wisdom, riches, righteousness, or fleshly privileges; but in the Lord, as the God of nature, providence, and grace; as a promising and covenant keeping God, who is to be trusted with all, and for every thing temporal and spiritual, and at all times.

He is their help and their shield; the help and shield of every true Israelite; of everyone that trusts in the Lord; or,

"your help and your shield, O ye Israelites;''

so Ben Balaam in Aben Ezra reads the words: which are a reason or argument encouraging trust in the Lord, since he is the help of his people; they are helpless in themselves, and vain is the help of man, for there is none in him; there is no help but in the Lord, and he is a present, seasonable, and sufficient help: Jehovah the Father has promised them help, and he is both able and faithful to make it good; he has laid help upon his Son for them; and has set up a throne of grace, where they may come for grace to help them in time of need: Christ has helped them out of the miserable estate they were fallen into by sin; he helps them on in their way to heaven, by his power and grace, and at last brings them thither: the Spirit of God helps them to the things of Christ; to many exceeding great and precious promises; and out of many difficulties, snares, and temptations; and he helps them in prayer under all their infirmities, and makes intercession for them, according to the will of God; and therefore they should trust in the Lord, Father, Son, and Spirit: and who is also "their shield", to protect and defend them from all dangers, evils, and enemies; what a shield is to the body, to secure it from hurt, that to the people of God are the love and favour of God, his power and might, his truth and faithfulness; as likewise Christ, his blood, righteousness, and salvation; and the Spirit, and his grace; see Psalm 5:12, Ephesians 6:16.
