In the grandeur and solemnity of a divine judgment, God is introduced as instructing men in the nature of true worship, exposing hypocrisy, warning the wicked, and encouraging the pious. (Psa. 50:1-23) The description of this majestic appearance of God resembles that of His giving the law (compare Exo 19:16; Exo 20:18; Deu 32:1).
