Psalms 21:3 - Coke's Commentary on the Holy Bible

For thou preventest him— The word in the original signifies to encompass. The rendering of Castalio is fully expressive of the sense; Thou hast bestowed most eminent favours on him. By the crown of pure gold, may be meant, in general, an illustrious crown; which is here represented as being set upon our blessed Saviour's head at his exaltation into heaven, in token of his being then advanced to the chief exercise of his regal authority. Thus he is said, Psalms 8:5 to be crowned with glory and honour; and St. John says, with respect to his deified humanity, in which he was made King of Kings and Lord of Lords, that on his head were many crowns. Revelation 12:16.
