Elihu professes to speak by the inspiration of the Holy Spirit, and corrects both parties. He allowed that those who had the longest experience should speak first. But God gives wisdom as he pleases; this encouraged him to state his opinion. By attention to the word of God, and dependence upon the Holy Spirit, young men may become wiser than the aged; but this wisdom will render them swift to hear, slow to speak, and disposed to give others a patient hearing.

Volume 1-7
10. Therefore. In view of the fact that wisdom is a gift of God, and is not limited to age or station, Elihu makes bold to express his opinion.
