For I have known that the Lord is great, and our God is above all gods.

“..."Because," says he, "I know that the Lord is great, and our God is above all gods" [Psalm 135:5]. If we should say to him, we ask thee, explain to us His greatness; would he not perchance answer us, He whom I see is not so very great, if He be able to be expounded by me. Let him then return to His works, and tell us. Let him hold in his conscience the greatness of God, which he has seen, which he has committed to our faith, whither he could not lead our eyes, and enumerate some of the things which the Lord hath done here; that unto us, who cannot see His greatness as he can, He may become sweet through the works of His which we can comprehend....”

“For I know that the Lord is great,.... Jehovah the Father is great in his perfections; in his power, wisdom, faithfulness, grace, and goodness; and in his works of creation, providence, and grace: and so is Jehovah the Son, who seems chiefly designed, who is called "our Lord" or "Adon" in the next clause; he is great, having the same perfections his Father has; and doing the same works, besides the miracles he wrought here on earth, and the great work of our redemption: he is the great God and our Saviour, and a great Saviour he is; and indeed he is great in all his offices of Prophet, Priest, and King: and so is the blessed Spirit, who is equal to the Father and Son, and greater than he that is in the world. Now all this the psalmist could say from his own knowledge; he knew the Lord was great, from the consideration and meditation of his wondrous works; he knew the greatness of Christ, from the revelation made to him of his person, offices, and grace; he knew the greatness of the divine Spirit, from the inward experience of his upon his heart, as well as from his being divinely inspired by him; and because of this greatness of the Lord, as well as his goodness, he is to be praised; it is mentioned as a reason of it; and that our Lord is above all gods; the Lord our righteousness; Immanuel, God with us: our Lord, not only by right of creation, but of redemption; he is above all that the Heathens called gods, even the greatest of them; not the idols their hands made only, but the heavens and all the host of them, the sun, moon, and stars; his glory is above them, being the Maker of them, as God; and he is made higher than they, as man and Mediator: he is above civil magistrates, princes, and kings of the earth, called gods, Psa 82:5; he is King of kings, and Lord of lords, he is higher than they; by him they reign, and to him they are accountable; and he is above the angels, sometimes called "Elohim", or gods, Psa 8:5; he has a more excellent name and nature than they; he is the Creator of them, the object of their worship, to whom they minister, whose servants they are; and he is now exalted above them in the human nature, at the right hand of God; see Heb 1:4.”

“The praise itself now begins. כּי in Psa 135:4 set forth the ground of the pleasant duty, and the כי that begins this strophe confirms that which warrants the summons out of the riches of the material existing for such a hymn of praise. Worthy is He to be praised, for Israel knows full well that He who hath chosen it is the God of gods. The beginning is taken from Psa 115:3, and Psa 135:7 from Jer 10:13 (Psa 51:16). Heaven, earth, and water are the three kingdoms of created things, as in Exo 20:4. נשׂיא signifies that which is lifted up, ascended; here, as in Jeremiah, a cloud. The meaning of בּרקים למּטר עשׂה is not: He makes lightnings into rain, i.e., resolves them as it were into rain, which is unnatural; but either according to Zac 10:1 : He produces lightnings in behalf of rain, in order that the rain may pour down in consequence of the thunder and lightning, or poetically: He makes lightnings for the rain, so that the rain is announced (Apollinaris) and accompanied by them. Instead of מוצא (cf. Psa 78:16; Psa 105:43), which does not admit of the retreating of the tone, the expression is מוצא, the ground-form of the part. Hiph. for plurals like מחצרים, מחלמים, מעזרים, perhaps not without being influenced by the ויּוצא in Jeremiah, for it is not מוצא from מצא that signifies "producing," but מוציא = מפיק. The metaphor of the treasuries is like Job 38:22. What is intended is the fulness of divine power, in which lie the grounds of the origin and the impulses of all things in nature.”
