Adam Clarke's Bible Commentary Verse 7. Days should speak ] That is, men are to be reputed wise and experienced in proportion to the time they have lived. The Easterns were remarkable for treasuring up wise sayings: indeed, the principal part of their boasted wisdom consisted in proverbs and maxims on different subjects.
Matthew Henry Commentary
Verses 6-14 - Elihu professes to speak by the inspiration of the Holy Spirit, an corrects both parties. He allowed that those who had the longes experience should speak first. But God gives wisdom as he pleases; thi encouraged him to state his opinion. By attention to the word of God and dependence upon the Holy Spirit, young men may become wiser tha the aged; but this wisdom will render them swift to hear, slow to speak, and disposed to give others a patient hearing.
