30:4, there is a prophetic notice of Him who came down from heaven to be our Instructor and Saviour, and then ascended into heaven to be our Advocate. The Messiah is here spoken of as a Person distinct from the Father, but his name as yet secret. The great Redeemer, in the glories of his providence and grace, cannot be found out to perfection. Had it not been for Christ, the foundations of the earth had sunk under the load of the curse upon the ground, for man's sin. Who, and what is the mighty One that doeth all this? There is not the least ground to suspect anything wanting in the word of God; adding to his words opens the way to errors and corruptions.
2-4. brutish—stupid, a strong term to denote his lowly self-estimation; or he may speak of such as his natural condition, as contrasted with God's all-seeing comprehensive knowledge and almighty power. The questions of this clause emphatically deny the attributes mentioned to be those of any creature, thus impressively strengthening the implied reference of the former to God (compare De 30:12-14; Isa 40:12; Eph 4:8).
