Psalms 45:4 - Wesley's Explanatory Notes

And — Being thus magnificently girt and armed. Ride — March on speedily and successfully against thine enemies. The word — That is, the gospel: which is called the word of truth, Ephesians 1:13, and may no less truly be called the word of meekness, because it is not delivered with terror, as the law was at Sinai, but meekly and sweetly; and the word of righteousness, because it brings in everlasting righteousness, and strongly excites all men to the practice of righteousness and holiness. And so the gospel is compared, to an horse or chariot, upon which Christ is said to ride, when the gospel is preached, and carried about from place to place. Teach thee — Thou shalt do exploits, which shall be terrible to thine enemies. But the phrase, thy right hand shall teach thee, is not to be taken properly; the meaning is, his hand should shew him, discover and work before him.
