Psalms 45:4 - Coke's Commentary on the Holy Bible

Ride prosperously— i.e. "Go forth, like a great conqueror, (see Revelation 19:11.) not to enslave men's persons, or to spoil their goods; but to settle the true faith among them, and to make them humble and meek, just and merciful." Thy right hand, &c. means, "Thy mighty power shall instruct thee to do miraculous and amazing works." See Luke 5:26Luk 5:26. Green renders this verse, Ride on successfully in the cause of truth, righteousness, and meekness; and let thy right hand direct thee to do formidable things: and others, And in thy majesty prosper thou: ride for the cause of truth, &c.
