John Gill's Exposition of the Whole Bible
Psalms 145:1
I will extol thee, my God, O King,.... Or "the King" a, the King Messiah, who is by way of eminency called "the King", as in
Psalms 21:1. This is the foundation of this whole psalm, as Aben Ezra observes; and shows who is intended and who is the subject of it that is spoken of throughout, even the Messiah, who is the King of the world, the King of the kings of it, the King of Zion, of his church and people, the King of saints, of all believers in him, by the appointment of God, by the conquest of his grace, over whom he reigns by his Spirit and grace; for this his kingdom is spiritual, is in righteousness, and everlasting: and this great King is not a creature, but God, the mighty God, David's Lord and God, and the Lord and God of every saint; whom David loved as such, believed in, looked unto for salvation; from whom he received grace and expected glory, and knew and claimed his interest in him, which is the great privilege of believers in him; see
John 20:28; and therefore they, as David, will extol him above all created beings, he being God over all; extol him above all men, even the best and greatest, Moses, Joshua, Aaron, Abraham, or any other, who are his creatures, his children, and his subjects; and even as man he is to be extolled above all men; being chosen out from among the people, fairer than the children of men, and the chiefest among ten thousand; and above the angels, having a more excellent name and nature than they; they being his creatures and servants, and he their Creator and the object of their worship: Christ is extolled by his people when they ascribe deity to him, magnify him in his offices, and make use of him in them all; attribute their whole salvation to him, think and speak highly of him, and declare him extolled and exalted at the right hand of God, as he now is, and as the Old Testament saints, as David and others, had a foresight of and rejoiced in, Psalms 110:1; the Septuagint, Syriac, Ethiopic, and Arabic versions, have it, "my King"; see Zechariah 9:9;
and I will bless thy name for ever and ever; by pronouncing him the Son of the Blessed, God over all blessed for ever; and by ascribing blessing, honour, glory, and power, unto him; by adoring and celebrating the perfections of his nature, which are his name, by which he is known; by expressing a high value and esteem for every precious name of his, as Immanuel, God with us; Jesus, a Saviour, c. and a regard to his everlasting Gospel, which is his name, bore by his ministering servants throughout the world see Psalms 8:1.
