Should he reason with unprofitable talk? - It does not become a man professing to be wise to make use of words that are nothing to the purpose. The sense is, that what Job said amounted to just nothing.

Should he reason with unprofitable talk? - Should a man talk disrespectfully of his Maker, or speak to him without reverence? and should he suppose that he has proved any thing, when he has uttered words of little meaning, and used sound instead of sense?

Should he reason with unprofitable talk?.... That is, the wise man, such a man as Job; does it become him to talk such idle stuff? that which is false, and foolish, and frothy, that does not minister grace to the hearer, and is not for the use of edifying; as whatever is untrue, unwise, vain, and empty, must be useless and answer no good end; nothing is profitable but what tends to increase solid wisdom and spiritual knowledge, and to exercise grace, and influence an holy life; wherefore what are profitable to the souls of men are the doctrines of the word of God, and the experiences of the grace of God, communicated by his people one to another; and nothing but these, or what agrees with them, should come out of the mouth of a wise and good man; nor can such an one expect to convince men of their errors, or reprove them for their sins with success, who deals in words of no profit:

or with speeches wherewith he can do no good? but may do a great deal of hurt both to himself and others; but the same thing is here signified in different words,

Should he reason with unprofitable talk? or with speeches wherewith he can do no good?

15:1-16 Eliphaz begins a second attack upon Job, instead of being softened by his complaints. He unjustly charges Job with casting off the fear of God, and all regard to him, and restraining prayer. See in what religion is summed up, fearing God, and praying to him; the former the most needful principle, the latter the most needful practice. Eliphaz charges Job with self-conceit. He charges him with contempt of the counsels and comforts given him by his friends. We are apt to think that which we ourselves say is important, when others, with reason, think little of it. He charges him with opposition to God. Eliphaz ought not to have put harsh constructions upon the words of one well known for piety, and now in temptation. It is plain that these disputants were deeply convinced of the doctrine of original sin, and the total depravity of human nature. Shall we not admire the patience of God in bearing with us? and still more his love to us in the redemption of Christ Jesus his beloved Son?
