An everlasting king.--Here, as in other like passages, the English Version is not wrong, but the Hebrew idiom "King of Eternity" is far grander.
he is the living God; that has life in himself, and is the author and giver of life to others; to all men natural life, to some men spiritual and eternal life; whereas the gods of the Gentiles have no life in themselves; are either dead men, or lifeless and inanimate things, stocks and stones, and can give no life to others. The words are in the plural number, "he is the living Gods"; not for the sake of honour and glory, as Kimchi observes; but as denoting a trinity of Persons in the unity of the divine essence: for though the words , "living Gods", that is, living divine Ones, or Persons, are in the plural number, yet "he", is in the singular; which is worthy of observation. The Syriac version renders it, "the God of the living"; and so an Oxford Arabic MS, see Matthew 22:32.
And an everlasting King; from everlasting to everlasting; he is King of old, even from eternity, and will ever be so; his kingdom is an everlasting one, and his throne for ever and ever, and he will always have subjects to reign over; nor will he have any successor, as mortal kings have, even such who have been deified by their idolatrous subjects.
At his wrath the earth shall tremble; that is, the inhabitants of it, when it is poured forth in judgments in the present life, and in the everlasting destruction of soul and body hereafter; and then shall they fear him, though now they do not.
And the nations shall not be able to abide his indignation; especially at the day of judgment; see Revelation 6:16.
