Psalms 50:1 - Joseph Benson’s Commentary on the Old and New Testaments

The mighty God, even the Lord Hebrew. Eel Elohim, Jehovah; the God of gods; Jehovah; the supreme Lord of heaven and earth, the Lawgiver and Judge of men and angels; to whom the greatest kings and potentates are but subjects; the infinite, the eternal, who changes not; hath spoken and called the earth, &c. Hath given forth his orders, that all the inhabitants of the earth, from one end to the other, should appear before him. These he now summons to be witnesses of his proceedings in this solemn judgment, between him and his people, which is here poetically represented. For here is a tribunal erected, the judge coming to it, the witnesses and delinquents summoned, and at last the sentence given, and cause determined.
