Praise, ye servants of Jehovah! This psalm contains abundant reasons for all men without exception to praise God. The faithful alone being endued with spiritual perception to recognize the hand of God, the prophet addresses them in particular. And if we consider how cold and callous men are in this religious exercise, we will not deem the repetition of the call to praise God superfluous. We all acknowledge that we are created to praise God's name, while, at the same time, his glory is disregarded by us. Such criminal apathy is justly condemned by the prophet, with the view of stirring us up to unwearied zeal in praising God. The repetition, then, of the exhortation to praise him, ought to be considered as referring both to perseverance and ardor in this service. If, by the servants of God, some would rather understand the Levites, to whom the charge of celebrating his praises under the Law was committed, I am not much opposed to it, provided they do not exclude the rest of the faithful, over whom formerly God appointed the Levites as leaders and chief musicians, that he might be praised by all his people without exception. When the Holy Spirit addresses the Levites expressly in relation to the subject of God's praises, it is designedly that, by their example, they may show the way to others, and that the whole Church may respond in one holy chorus. Now that we are all "a royal priesthood," (1-Peter 2:9) and as Zechariah testifies, (Zechariah 14:21) that under the reign of Christ, the meanest of the people shall be Levites, there is no question that, excepting unbelievers who are mute, the prophet invites us all in common to render this service unto God.

Praise ye the Lord - Margin, as in Hebrew, "Hallelujah." See the notes at Psalm 106:1.
Praise, O ye servants of the Lord - You who profess to serve and obey him; who acknowledge him as your God. In the original this is also the word "Hallelu," הללוּ halelû.
Praise the name of the Lord - Still the same word "Hallelu." The name of the Lord is put here, as it is often, for the Lord himself.

Praise, O ye servants - Probably an address to the Levites. The Anglo-Saxon has praise the Lord, ye knaves. Knapa or knave signified among our ancestors a servant; sometimes a male, a young man.

Praise ye the LORD. (a) Praise, O ye servants of the LORD, praise the name of the LORD.
(a) By this often repetition he stirs up our cold dullness to praise God, seeing his works are so wonderful, and that we are created for the same cause.

Praise ye the Lord,.... Or, "hallelujah". This is the title of the psalm, as in the two preceding, and directs to the principal matter of it.
Praise, O ye servants of the Lord; meaning not the angels, nor all men, nor the priests and Levites only; but all the saints, who are a holy priesthood, to offer up spiritual sacrifices to God; who are servants, not of sin, nor of Satan, nor of men, but of God and Christ; and who serve the Lord willingly and cheerfully, with much pleasure and delight, in righteousness and holiness, with reverence and godly fear, and without trusting to and depending on their service for salvation: and one principal branch of their service is praise, especially under the Gospel dispensation; in which all legal sacrifices are abolished, and the sacrifice of praise is continued; and which is pleasant and delightful work, and yet there is a backwardness to it; and therefore there is need of such an exhortation to excite unto it, and to repeat it, as follows:
praise the name of the Lord; not any particular name, as Jehovah; but him himself, and the perfections of his nature; his holiness, justice, truth, faithfulness, power, goodness, grace and mercy. The repetition of the exhortation denotes either the abundance of praise to be given to the Lord, or the constancy and continuance of it; which ought to be done at all times, every day, since his mercies are new every morning. Some have thought the threefold repetition respects the trinity of Persons, who are each to be praised, as in Numbers 6:24, but this is doubtful, and perhaps not sufficient to build such a doctrine on; and especially since the first of these exhortations is the title of the psalm: however, this is a certain truth, that Jehovah, Father, Son, and Spirit, are to be praised.

God has praise from his own people. They have most reason to praise him; for those who attend him as his servants, know him best, and receive most of his favours, and it is easy, pleasant work to speak well of their Master. God's name ought to be praised in every place, from east to west. Within this wide space the Lord's name is to be praised; it ought to be so, though it is not. Ere long it will be, when all nations shall come and worship before him. God is exalted above all blessing and praise. We must therefore say, with holy admiration, Who is like unto the Lord our God? How condescending in him to behold the things in the earth! And what amazing condescension was it for the Son of God to come from heaven to earth, and take our nature upon him, that he might seek and save those that were lost! How vast his love in taking upon him the nature of man, to ransom guilty souls! God sometimes makes glorious his own wisdom and power, when, having some great work to do, he employs those least likely, and least thought of for it by themselves or others. The apostles were sent from fishing to be fishers of men. And this is God's constant method in his kingdom of grace. He takes men, by nature beggars, and even traitors, to be his favourites, his children, kings and priests unto him; and numbers them with the princes of his chosen people. He gives us all our comforts, which are generally the more welcome when long delayed, and no longer expected. Let us pray that those lands which are yet barren, may speedily become fruitful, and produce many converts to join in praising the Lord.

God's majesty contrasted with His condescension and gracious dealings towards the humble furnish matter and a call for praise. The Jews, it is said, used this and Psalm 114-118 on their great festivals, and called them the Greater Hallel, or Hymn. (Psalm 113:1-9)
Earnestness and zeal are denoted by the emphatic repetitions.
servants of the Lord--or, all the people of God.
name of the Lord--perfections (Psalm 5:11; Psalm 111:9).

The call, not limited by any addition as in Psalm 134:1, or eve, after the manner of Psalm 103:20., extended over the earth, is given to the whole of the true Israel that corresponds to its election by grace and is faithful to its mission; and its designation by "servants of Jahve" (Ps 69:37, cf. Ps 34:23), or even "servant of Jahve" (Psalm 136:22), has come into vogue more especially through the second part of Isaiah. This Israel is called upon to praise Jahve; for the praise and celebration of His Name, i.e., of His nature, which is disclosed by means of its manifestation, is a principal element, yea, the proper ground and aim, of the service, and shall finally become that which fills all time and all space. מהלּל laudatum (est), is equivalent to ἀινετόν, laudabile (lxx, Vulgate), and this does not differ greatly from laudetur. The predictive interpretation laudabitur is opposed to the context (cf. moreover Kφhler on Malachi 1:11).
