Blessed is the people - Happy is their condition. See the notes at Psalm 1:1.

That know the joyful sound - That hear that sound. DeWette explains this of the call to the festivals and offerings, Leviticus 23:24; Numbers 10:10; Psalm 27:6. That is, says he, those who honor and worship God. The Hebrew word - תרועה terû‛âh - means a loud noise; a tumult; especially, shouts of joy, or rejoicing, Job 8:21; 1 Samuel 4:5; the "shout of a king," that is, the joyful acclamations with which a king is welcomed, Numbers 23:21; the shout of battle, Jeremiah 4:19; Jeremiah 49:2. Then it means the sound or clangor of trumpets, Leviticus 25:9; Numbers 29:1-6. The word is, therefore, especially applicable to the sounding of the trumpets which attended the celebration of the great; festivals among the Hebrews, and there can be little doubt that this is the reference here. The idea is, that they are blessed or happy who are the worshippers of Yahweh, the true God; who are summoned to his service; who are convened to the place of his worship.

They shall walk, O Lord, in the light of thy countenance - They shall live in thy favor, and enjoy thy smiles.

Blessed is the people - "O the blessednesses of that people (אשרי העם( elp ashrey haam) that know the joyful sound;" that are spared to hear the sound of the trumpet on the morning of the jubilee, which proclaims deliverance to the captives, and the restoration of all their forfeited estates. "They shall walk vigorously (יהלכון yehallechun) in the light of thy countenance" (באור פניך beor paneycha) - the full persuasion of the approbation of God their Father, Redeemer, and Sanctifier.

Blessed is the people that know the joyful sound,.... Of the love, grace, and mercy of God displayed in Christ, of peace and pardon by his blood, of justification by his righteousness, of atonement by his sacrifice, and of complete salvation by his obedience, sufferings, and death; this is the sound of the Gospel, and a joyful one it is to sensible sinners; and is so called in allusion either to a shout made upon a victory gained, and such a sound is the Gospel; it declares victory by Christ over sin, Satan, the world, and death, and every enemy; and that he has made his people more than conquerors over them; or to the jubilee trumpet, which proclaimed liberty and a restoration of inheritances, Leviticus 25:9 and so the Gospel proclaims liberty to the captives, freedom from the dominion of sin, and condemnation by it, from the tyranny of Satan, and the bondage of the law; and gives an account of the inheritance the saints have in Christ, and through his death, to which they are regenerated, and for which they are made meet by the Spirit of God, and of which he is the seal and earnest: or to the silver trumpets, for the use of the congregation of Israel, and blown at their solemn feasts, and other times, and were all of a piece, Numbers 10:1, the trumpet of the Gospel gives a certain sound, an even one, a very musical one; there is no jar nor discord in it; is a soul charming alluring sound, and very loud; it has reached, and will reach again, to the ends of the earth, Romans 10:18, it is a blessing to hear it, but it is a greater to "know" it, not merely notionally, but spiritually and experimentally; so as not only to approve of it, and be delighted with it, but so as to distinguish it from all other sounds; and by faith to receive it, and appropriate the things it publishes to a man's own soul; and such must be "blessed", or happy persons, for the reasons following in this verse, and in Psalm 89:16,

they shall walk, O Lord, in the light of thy countenance: enjoy the gracious presence of God, have the manifestation of himself, the discoveries of his love, communion with him through Christ, and the comforts of the Holy Spirit, and these continued; so that they shall walk in the sunshine of these things, though not always; for sometimes they walk in darkness, and see no light; but it is an unspeakable mercy and blessing to walk herein at any time, for ever so short a season, see Psalm 4:6.

15 Blessed is the people that know the joyful sound: they shall walk, O Lord, in the light of thy countenance,

16 In thy name shall they rejoice all the day: and in thy righteous shall they be exalted.

17 For thou art the glory of their strength: and in thy favour our how shall be exalted.

18 For the Lord is our defence; and the Holy One of Israel is our king.

Psalm 89:15

"Blessed is the people that know the joyful sound." He is a blessed God of whom the Psalmist has been singing, and therefore they are a blessed people who partake of his bounty, and know how to exult in his favour. Praise is a peculiarly joyful sound, and blessed are those who are familiar with its strains. The covenant promises have also a sound beyond measure precious, and they are highly favoured who understand their meaning and recognise their own personal interest in them, There may also be a reference here to the blowing of trumpets and other gladsome noises which attended the worship of Jehovah, who, unlike the gods of the heathen was not adored by the shrieks of wretched victims, or the yells and outcries of terror-stricken crowds, but by the joyful shouts of his happy people. "They shall walk, O Lord, in the light of thy countenance." For them it is joy enough that Jehovah is favourable to them; all day long this contents them and enables them with vigour to pursue their pilgrimage. Only a covenant God could look with favour upon men, and those who have known him in that relationship learn to rejoice in him, yea, to walk with him in fellowship, and to continue in communion with him we give God our ear and hear the joyful sound, he will shew us his face and make us glad. While the sun shines, men walk without stumbling as to their feet, and when the Lord smiles on us we live without grief as to our souls.

Psalm 89:16

"In thy name shall they rejoice all the day." And good cause they have for so doing, for to the soul which, in Christ Jesus, has entered into covenant with God, every attribute is a fountain of delight. There is no hour in the day, and no day in our life, in which we may not rejoice in the name, person, and character of the Lord. We need no other reason for rejoicing. As philosophers could make merry without music, so can we rejoice without carnal comforts; the Lord All-sufficient is an all-sufficient source of joy. "And in thy righteousness, shall they be exalted." By the Lord's righteous dealings the saints are uplifted in due time, however great may have been the oppression and the depression from which they may have suffered. In the righteousness which the covenant supplies, which is entirely of the Lord, believers are set on high, in a secure and blessed position, so that they are full of sacred happiness. If God were unjust, or if he regarded us as being without righteousness, we must be filled with misery, but as neither of these things is so, we are exalted indeed, and would extol the name of the Lord.

Psalm 89:17

"For thou art the glory of their strength." Surely in the Lord Jehovah have we both righteousness and strength. He is our beauty and glory when we are strong in him, as well as our comfort anti sustenance when we tremble because of conscious weakness in ourselves. No man whom the Lord makes strong may dare to glory in himself, he must ascribe all honour to the Lord alone; we have neither strength nor beauty apart from him. "And in thy favour our horn shall be exalted." By the use of the word our the Psalmist identifies himself with the blessed people, and this indicates how much sweeter it is to sing in the first person than concerning others. May we have grace to claim a place among those in covenant with God, in Christ Jesus, for then a sense of divine favour will make us also bold and joyous. A creature full of strength and courage lifts up its horn, and so also does a believer become potent, valiant, and daring. The horn was an eastern ornament, worn by men and women, or at least is so at this day, and by the uplifting of this the wearer showed himself to be in good spirits, and in a confident frame of mind: we wear no such outward vanities, but our inward soul is adorned and made bravely triumphant when the favour of God is felt by us. Worldly men need outward prosperity to make them lift up their heads, but the saints find more than enough encouragement in the secret love of God.

Psalm 89:18

"For the Lord is our defence." Whoever else may defend us, he is our ultimate Defender and Shield. "And the Holy One of Israel is our king." He who protects should govern, our defender should be acknowledged as our king. Kings are called the shields of nations, and the God of Israel is both our Ruler and Defence. Another sense may be that Israel's defender and king was of the Lord, belonging to him and sent by him; even the protectors of the land being themselves protected by the Lord. The title "the Holy One of Israel" is peculiarly delightful to the renewed heart. God is one, we worship none beside. He is holiness itself, the only being who can be called "the Holy One," and in his perfection of character we see the most excellent reason for our faith. He who is holy cannot break his promises, or act unjustly concerning his oath and covenant. Moreover, he is the Holy One of Israel, being specially the God of his own elect, ours by peculiar ties, ours for ever and ever. Who among the saints will not rejoice in the God of election? Are they not indeed a people greatly blessed who can call this God their God for ever and ever?

The poet has now described what kind of God He is upon whose promise the royal house in Israel depends. Blessed, then, is the people that walks in the light of His countenance. הלּך of a self-assured, stately walk. The words ידעי תּרוּעה are the statement of the ground of the blessing interwoven into the blessing itself: such a people has abundant cause and matter for exultation (cf. Psalm 84:5). תּרוּעה is the festive sound of joy of the mouth (Numbers 23:21), and of trumpets or sackbuts (Psalm 27:6). This confirmation of the blessing is expanded in Psalm 89:17-19. Jahve's שׁם, i.e., revelation or manifestation, becomes to them a ground and object of unceasing joy; by His צדקה, i.e., the rigour with which He binds Himself to the relationship He has entered upon with His people and maintains it, they are exalted above abjectness and insecurity. He is תּפארת עזּמו, the ornament of their strength, i.e., their strength which really becomes an ornament to them. In Psalm 89:18 the poet declares Israel to be this happy people. Pinsker's conjecture, קרנם (following the Targum), destroys the transition to Psalm 89:19, which is formed by Psalm 89:18. The plural reading of Kimchi and of older editions (e.g., Bomberg's), קרנינוּ, is incompatible with the figure; but it is immaterial whether we read תּרים with the Chethb (Targum, Jerome), or with the Ker (lxx, Syriac) תּרוּם.

(Note: Zur Geschichte des Karaismus, pp. קפא and קפב, according to which, reversely, in Joshua 5:1 עברוּ is to be read instead of עברם, and Isaiah 33:2 זרענוּ instead of זרעם, Psalm 12:8 תשמרנּוּ instead of תשמרם, Micah 7:19 חטאתנוּ instead of חטאתם, Job 32:8 תביננּוּ instead of תבינם, Proverbs 25:27 כבודנוּ instead of כבודם (the limiting of our honour brings honour, - an unlikely interpretation of the חקר).)

מגנּנוּ and מלכּנוּ in Psalm 89:19 are parallel designations of the human king of Israel; מגן as in Psalm 47:10, but not in Psalm 84:10. For we are not compelled, with a total disregard of the limits to the possibilities of style (Ew. 310, a), to render Psalm 89:19: and the Holy One of Israel, (as to Him, He) is our King (Hitzig), since we do not bring down the Psalm beyond the time of the kings. Israel's shield, Israel's king, the poet says in the holy defiant confidence of faith, is Jahve's, belongs to the Holy One of Israel, i.e., he stands as His own possession under the protection of Jahve, the Holy One, who has taken Israel to Himself for a possession; it is therefore impossible that the Davidic throne should become a prey to any worldly power.

Blessed is the people that {m} know the joyful sound: they shall walk, O LORD, in the light of thy {n} countenance.

(m) Feeling in their conscience that God is their father.

(n) They will be preserved by your fatherly providence.

89:15 Know - Who enjoy the presence of God and his ordinances, to which they are called by the sound of trumpets. Walk - Under the comfortable influences of thy favour.

15. His government of righteousness is served by "mercy" and "truth" as ministers (Ps 85:10-13).

know the joyful sound-understand and appreciate the spiritual blessings symbolized by the feasts to which the people were called by the trumpet (Le 25:9, &c.).

walk . countenance-live in His favor (Ps 4:6; 44:3).

89:15-18 Happy are those who so know the joyful sound of the gospel as to obey it; who experience its power upon their hearts, and bring forth the fruit of it in their lives. Though believers are nothing in themselves, yet having all in Christ Jesus, they may rejoice in his name. May the Lord enable us to do so. The joy of the Lord is the strength of his people; whereas unbelief dispirits ourselves and discourages others. Though it steals upon us under a semblance of humility, yet it is the very essence of pride. Christ is the Holy One of Israel; and in him was that peculiar people more blessed than in any other blessing.
