Charles H. Spurgeon on Psalms 135:1

Praise, praise, praise. When duties are thus inculcated, it notes the necessity and excellency thereof; together with our dulness and backwardness thereunto. —John Trapp.

Verses 1-2, 21. Praise. To prevent any feeling of weariness which might arise from the very frequent repetition of this exhortation to praise God, it is only necessary to remember that there is no sacrifice in which he takes greater delight than in the expression of praise. Thus (Ps 1:14), "Sacrifice unto the Lord thanksgiving, and pay thy vows unto the Most High; "and (Ps 116:12-13), "What shall I render unto the LORD for all his benefits toward me? I will take the cup of salvation, and call upon the name of the LORD." Particular attention is to be paid to those passages of Scripture which speak in such high terms of that worship of God which is spiritual; otherwise we may be led, in the exercise of a misguided zeal, to spend our labour upon trifles, and in this respect imitate the example of too many who have wearied themselves with ridiculous attempts to invent additions to the service of God, while they have neglected what is of all other things most important. That is the reason why the Holy Spirit so repeatedly inculcates the duty of praise. It is that we may not undervalue, or grow careless in this devotional exercise. It implies, too, an indirect censure of our tardiness in proceeding to the duty; for he would not reiterate the admonition were we ready and active in the discharge of it. —John Calvin.

Verses 1-3. As Gotthold was one day passing a tradesman's house, he heard the notes of a Psalm, with which the family were concluding their morning meal. He was deeply affected, and, with a full heart, said to himself: O my God, how pleasing to my ears is the sound of thy praise, and how comforting to my soul the thought that there are still a few who bless thee for thy goodness. Alas, the great bulk of mankind have become brutalized, and resemble the swine, which in harvest gather and fatten upon the acorns beneath the oak, but show to the tree, which bore them, no other thanks than rubbing off its bark, and tearing up the sod around it. In former times, it was the law in certain monasteries, that the chanting of the praise of God should know no interruption, and that one choir of monks should, at stated intervals, relieve another in the holy employment. To the superstition and trust in human works, of which there may have been here a mixture, we justly assign a place among the wood, hay, and stubble (1Co 3:12). At the same time it is undeniably right that thy praise should never cease; and were men to be silent, the very stones would cry out. We must begin eternal life here below, not only in our conscience, but also with our praise. Our soul ought to be like a flower, not merely receiving the gentle influence of heaven, but, in its turn, and as if in gratitude, exhaling also a sweet and pleasant perfume. It should be our desire, as it once was that of a pious man, that our hearts should melt and dissolve like incense in the fire of love, and yield the sweet fragrance of praise: or we should be like the holy martyr who professed himself willing to be consumed, if from his ashes a little flower might spring and blossom to the glory of God. We should be ready to give our very blood to fertilize the garden of the church, and render it more productive of the fruit of praise. Well then, my God, I will praise and extol thee with heart and mouth to the utmost of my power. Oh, that without the interruptions which eating, and drinking, and sleep require, I could apply myself to this heavenly calling! Every mouthful of air which I inhale is mixed with the goodness which preserves my life; let every breath which I exhale be mingled at least with a hearty desire for thy honour and praise. Hallelujah! Ye holy angels, ye children of men, and all ye creatures, praise the Lord with me, and let us exalt his name together. —Christian Scriver Gotthold,1629-1693.
