Praise him for his mighty acts - See the notes at Psalm 145:4 : "One generation shall praise thy works to another, and shall declare thy mighty acts." The Hebrew word is the same. The reference is to that which displays the power of God; the things which manifest his omnipotence.

Praise him according to his excellent greatness - Hebrew, the multitude of his greatness. Let the praise in elevation correspond with this; let it be such as shall properly express this; let all be employed that will contribute to make this known, or that will be appropriate to this. Hence, the psalmist proceeds to call on all to make use of everything, by instrument and voice, that would in any manner set forth the praise of God.

For his mighty acts - Whether manifested in creation, government, mercy or justice.

His excellent greatness - כרב גדלו kerob gudlo, according to the multitude of his magnitude, or of his majesty. After the manyfoldness of his mickleness - Anglo-Saxon. After the mykelnes of his greathede - Old Psalter. Let the praise be such as is becoming so great, so holy, and so glorious a Being.

Praise him for his mighty acts,.... The creation of all things out of nothing; the sustaining of all beings; the government of the world; the redemption of man by Christ, and the wonderful works done by him on earth; the work of grace upon the hearts of his people, and the preservation of them in grace to glory;

praise him according to his excellent greatness; or, "according to the multitude of his greatness" (t); which appears in his nature, perfections, and work, and these both of providence and grace; and in proportion hereunto, and according to the abilities of creatures, angels, and men, is he to be praised; which is giving him the honour due unto his name; see Psalm 96:8.

(t) "secundum multudinem magnitudinie ejus", V. L. Montanus, Gejerus; so Ainsworth.

Praise him for his mighty acts: praise him according to his excellent greatness.

2. mighty acts-(Ps 145:4).

excellent greatness-or, abundance of greatness.

150:1-6 A psalm of praise. - We are here stirred up to praise God. Praise God for his sanctuary, and the privileges we enjoy by having it among us; praise him because of his power and glory in the firmament. Those who praise the Lord in heaven, behold displays of his power and glory which we cannot now conceive. But the greatest of all his mighty acts is known in his earthly sanctuary. The holiness and the love of our God are more displayed in man's redemption, than in all his other works. Let us praise our God and Saviour for it. We need not care to know what instruments of music are mentioned. Hereby is meant that in serving God we should spare no cost or pains. Praise God with strong faith; praise him with holy love and delight; praise him with entire confidence in Christ; praise him with believing triumph over the powers of darkness; praise him by universal respect to all his commands; praise him by cheerful submission to all his disposals; praise him by rejoicing in his love, and comforting ourselves in his goodness; praise him by promoting the interests of the kingdom of his grace; praise him by lively hope and expectation of the kingdom of his glory. Since we must shortly breathe our last, while we have breath let us praise the Lord; then we shall breathe our last with comfort. Let every thing that hath breath praise the Lord. Praise ye the Lord. Such is the very suitable end of a book inspired by the Spirit of God, written for the work of praise; a book which has supplied the songs of the church for more than three thousand years; a book which is quoted more frequently than any other by Christ and his apostles; a book which presents the loftiest ideas of God and his government, which is fitted to every state of human life, which sets forth every state of religious experience, and which bears simple and clear marks of its Divine origin.
