He teareth me in his wrath - The language here is all taken from the ferocity of wild beasts; and the idea is, that his enemy had come upon him as a lion seizes upon its prey. Rosenmuller, Reiske, and some others suppose that this refers to God. Cocceius refers it to Satan. Schultens, Dr. Good, and some others, to Eliphaz, as the leading man among his adversaries. I have no doubt that this is the true reference. The connection seems to demand this; and we ought not to suppose that Job would charge this upon God, unless there is the clearest evidence. The whole passage is a description of the manner in which Job supposed his friends had come upon him. He says they had attacked him like wild beasts. Yet it must be admitted that he sometimes attributes these feelings to God, and says that he came upon him like a roaring lion see Job 10:16-17.
Who hateth me - Or rather, "and persecutes me, or is become my adversary," for so the word used here (שׂטם śâṭam) means; see the notes at Job 30:21.
He gnasheth upon me with his teeth - As an enraged wild animal does when about to seize upon its prey. A similar figure occurs in Otway, in his "Orphan:"
- For my Castalio's false;
False as the wind, the water, or the weather:
Cruel as tigers o'er their trembling prey:
I feel him in my breast, he tears my heart,
And at each sigh he drinks the gushing blood.
And so Homer, when he describes the wrath of Achilles as he armed himself to avenge the death of Patroclus, mentions among other signs of wrath his gnashing his teeth:
Τοῦ καὶ ὀδόντων μὲν καναχὴ πέλε.
Tou kai odontōn men kanachē pele.
Iliad xix. 364.
So Virgil describes his hero as
furens animis, dentibus infrendens.
Aeneid viii. 228.
Mine enemy sharpeneth his eyes upon me - Looks fiercely; watches me narrowly - as an animal does his victim when about to seize upon it. The image is probably drawn from the intense gaze of the lion when about to pounce upon his prey. "He darts piercing looks at me; or looks at me with a fierce and penetrating eye."

He teareth me in his wrath - Who the person is that is spoken of in this verse, and onward to the end of the fourteenth, has been a question on which commentators have greatly differed. Some think God, others Eliphaz, is intended: I think neither. Probably God permitted Satan to show himself to Job, and the horrible form which he and his demons assumed increased the misery under which Job had already suffered so much. All the expressions, from this to the end of the fourteenth verse, may be easily understood on this principle; e.g., Job 16:9 : "He (Satan) gnasheth upon me with his teeth; mine enemy sharpeneth his eyes upon me." Job 16:10 : "They (demons) have gaped on me with their mouth; - they have gathered themselves together against me." Job 16:11 : "God hath delivered me to the ungodly, (עויל avil, to the Evil One), and turned me over into the hands of the wicked." He hath abandoned me to be tortured by the tempter and his host. If we consider all these expressions as referring to Job's three friends, we must, in that case, acknowledge that the figures are all strained to an insufferable height, so as not to be justified by any figure of speech.

(k) He teareth [me] in his wrath, who hateth me: he gnasheth upon me with his teeth; mine enemy sharpeneth his eyes upon me.
(k) That is, God by his wrath: and in this diversity of words and high style, he expresses how grievous the hand of God was on him.

He teareth me in his wrath, who hateth me,.... By whom is meant not Satan, as Jarchi, though he is an enemy to, and an hater of mankind, especially of good men; nor Eliphaz, as others, who had fallen upon Job with a great deal of wrath and fury, tearing his character in pieces, which Job attributed to his hatred of him; but it rather appears from the context that God himself is intended, of whom Job had now a mistaken notion and apprehension; taking him for his enemy, being treated by him, as he thought, as if he had an aversion to him, and an hatred of him; whereas God hates none of his creatures, being his offspring, and the objects of his tender care, and providential regard: indeed sin is hateful to him, and makes men odious in his sight, and he hates all the workers of iniquity, and those whom he passed by, when he chose others; though they are said to be hated by him as Esau was, yet not with a positive but a negative hatred; that is, are not loved by him; and considered as profane and ungodly persons, and as such foreordained to condemnation; for sin may be said to be hated, but good men never are; God's chosen ones, his children and special people, are the objects of his everlasting love; and though he may be angry with them, and show a little seeming wrath towards them, yet never hates them; hatred and love are as opposite as any two things can possibly be; and indeed, strictly and properly speaking, there is no wrath nor fury in God towards his people; though they deserve it, they are not appointed to it, but are delivered from it by Christ; and neither that nor any of the effects of it shall ever light on them; but Job concluded this from the providence he was under, in which God appeared terrible to him, like a lion or any such fierce and furious creature, to which he is sometimes compared, and compares himself, which seizes on its prey, and tears and rends it to pieces; Isaiah 38:13; thus God permitted Job's substance to be taken from him by the Chaldeans and Sabeans; his children by death, which was like tearing off his limbs; and his skin and his flesh to be rent and broken by boils and ulcers: Job was a type of Christ in his sorrows and sufferings; and though he was not now in the best frame of mind, the flesh prevailed, and corruptions worked, and he expressed himself in an unguarded manner, yet perhaps we shall not find, in any part of this book, things expressed, and the language in which they are expressed, more similar and to be accommodated to the case, and sorrows, and sufferings of Christ, than in this context; for though he was the son of God's love, his dear and well beloved son, yet as he was the surety of his people, and bore and suffered punishment in their stead, justice behaved towards him as though there was a resentment unto him, and an aversion of him; yea, he says, "thou hast cast off and abhorred, thou hast been wroth with thine Anointed" or "Messiah", Psalm 89:38; and indeed he did bear the wrath of God, the vengeance of justice or curse of the righteous law; and was suffered to be torn in every sense, his temples with a crown of thorns, his cheeks by those that plucked off the hair, his hands and feet by the nails driven in them, and his side by the spear; and his life was torn, snatched, and taken away from him in a violent manner:
he gnasheth upon me with his teeth; as men do when they are full of wrath and fury: this is one way of showing it, as the enemies of David, a type of Christ, and the slayers of Stephen, his protomartyr, did, Psalm 35:16; and as beasts of prey, such as the lion, wolf, do:
mine enemy sharpeneth his eyes upon me; the Targum adds, as a razor. Here again Job considers God as his enemy, though he was not, misinterpreting his dealings with him; he represents him as looking out sharp after him, inspecting narrowly into all his ways, and works, and actions, strictly observing his failings and infirmities, calling him to an account, and afflicting him for them, and dealing rigidly and severely with him for any small offence: his eyes seemed to him to be like flames of fire, to sparkle with wrath and revenge; his thee, as he imagined, was set against him, and his eyes upon him to destroy him; and thus the eye of vindictive justice was upon Christ his antitype, when he was made sin and a curse for his people, and the sword of justice was awaked against him, and thrust in him.

Image from a wild beast. So God is represented (Job 10:16).
who hateth me--rather, "and pursues me hard." Job would not ascribe "hatred" to God (Psalm 50:22).
mine enemy--rather, "he sharpens, &c., as an enemy" (Psalm 7:12). Darts wrathful glances at me, like a foe (Job 13:24).

Eyes - Looks upon me with a fierce, and sparkling eye, as enraged persons use to do.
