That thou turnest thy spirit - That your mind is turned against God instead of acquiescing in his dealings. The views of Job he traces to pride and to overweening self-confidence, and perhaps not improperly.

That thou turnest thy spirit against God - The ideas here seem to be taken from an archer, who turns his eye and his spirit - his desire - against the object which he wishes to hit; and then lets loose his arrow that it may attain the mark.

That thou turnest thy spirit against God,.... Not against men, his friends only, but against God himself, being filled with wrath and indignation at him; showing the enmity of his heart unto him, and committing hostilities upon him, stretching out his hand, and strengthening himself against him, running upon him, on the thick bosses of his buckler, as after expressed:

and lettest such words go out of thy mouth? as in Job 9:22.

That thou turnest thy spirit against God, and lettest such words go out of thy mouth?

15:13 Against God - Eliphaz here does in effect give the cause on Satan's side, and affirms that Job had done as he said he would, Curse God to his face.

13. That is, frettest against God and lettest fall rash words.

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?
