Thine own mouth condemneth thee - That is, the sentiments which you have uttered show that you cannot be a pious man.

Thine own mouth condemneth thee, and not I,.... Or shows thee to be a wicked person, guilty of things charged upon thee; out of thine own mouth thou art convicted, there needs no other evidence to be brought against thee, that is sufficient: and thou savest me, and any other, the trouble of passing the sentence of condemnation upon thee; thou hast done it thyself, thine own mouth is judge and jury, and brings in the verdict, and pronounces it, as well as is the witness, as follows, and is instead of a thousand witnesses, Job 9:20;

yea, thine own lips testify against thee; and therefore there were no need of producing any other testimony; what he had said showed that his talk was vain and unprofitable, unbecoming a wise man, and tending to make null and void the fear of God among men, to discourage all religious exercises, and particularly prayer before God.

Thine own mouth condemneth thee, and not I: yea, thine own lips testify against thee.

6. No pious man would utter such sentiments.

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?
