Job 12:9 - Joseph Benson’s Commentary on the Old and New Testaments

Who knoweth not in all these Or, by all these brute creatures; that the hand of the Lord hath wrought this That God, by his power and wisdom, hath created and ordered all that is in them, or that is done by and among them. Job meant in these verses to express his firm opinion that all animate and inanimate nature clearly bore testimony to the creating power and overruling providence of God: see Nehemiah 9:6. This is the only time that we meet with the name Jehovah in all the discourses between Job and his friends. For God in that age was more known by the name of Shaddai, the Almighty.
