Eye
The eye is treated across UPDV as a divinely formed sense-organ that nevertheless requires constant discipline. The same faculty that registers a well of water or an angel in the road can also be sent chasing after vanity, evil, and forbidden bodies. The figure runs in two directions at once: the eye of the human, hazardous and prone to wandering, and the eye of Yahweh, sleepless and far brighter than the sun.
The Created Sense-Organ
The eye sits in the middle of a created triad. "He formed for them tongue, and eyes, and ears, And gave them a heart to understand" (Sir 17:7). It is given alongside the tongue and ear and paired with a heart that understands what the senses bring in.
When the eye is wounded, the body answers with a visible outflow, and the sage uses that outflow as a figure for relational rupture: "A wound in the eye makes tears flow, And a wound in the heart severs friendship" (Sir 22:19).
Eye Discipline and the Averted Gaze
Because the eye is an avenue into the heart, the wisdom literature treats it as something to be aimed and, when necessary, shut. The disciple is told, "Let your eyes look right on, And let your eyelids look straight before you" (Pr 4:25). The psalmist asks for the same redirection from above: "Turn away my eyes from looking at vanity, And quicken me in your ways" (Ps 119:37). And the prohibition is plain: "Do not go after your heart and your eyes, To walk in the pleasures of evil" (Sir 5:2).
The prophet describes the one who may dwell with the everlasting burnings as, among other things, the one "who shuts his eyes from looking on evil" (Is 33:15) — a positive closure of the eye, not a passive look-elsewhere.
Job extends this discipline by covenant with his own eye: "I made a covenant with my eyes; How then should I look at a virgin?" (Job 31:1). The sage echoes the same restraint: "Do not think about a virgin; Or else you will be snared by her fines" (Sir 9:5); "Hide your eye from a graceful woman; And do not look at beauty that is not yours. On account of a woman many have been destroyed; And so she will burn her lovers with fire" (Sir 9:8). Even the prayer-form is given: "Do not give me a proud look, And turn away lust from me" (Sir 23:5). The opposite faculty — the unguarded eye — is exposed in the warning, "Your eyes will make a fool of yourself in a vision; And you will be made desolate behind her house" (Sir 9:7), and in the diagnostic note that "the whoredom of a woman is in the lifting up of her eyes. And she is known by her eyelids" (Sir 26:9). The shameless eye is to be watched: "Look well after a shameless eye, And do not marvel if it trespasses against you" (Sir 26:11).
The Unsatisfied Eye
A second figure runs underneath the first. The eye, left to itself, has no full point. "Sheol and Abaddon are never satisfied; And the eyes of man are never satisfied" (Pr 27:20). The Preacher reads the same fact off ordinary experience: "All things are full of weariness; man can't utter [it]: the eye is not satisfied with seeing, nor the ear filled with hearing" (Ec 1:8). The apostolic restatement is brief: "For all that is in the world, the desire of the flesh and the desire of the eyes and the vainglory of life, is not of the Father, but is of the world" (1Jn 2:16).
The David-and-Bathsheba scene is the unsatisfied eye in narrative form: "from the roof he saw a woman bathing; and the woman was very beautiful to look at. And David sent and inquired after the woman... And David sent messengers, and took her; and she came in to him, and he plowed her" (2Sa 11:2-4). The chain begins at the eye on the roof.
The Evil Eye
The wisdom tradition also names a settled state of the eye, not just an episode of looking. "To the small of heart, riches are not seemly; And to the man who has an evil eye, gold is not seemly" (Sir 14:3). "In the eye of him who stumbles, his portion is little; And he who takes the portion of his fellow man, wastes his own portion" (Sir 14:9). "The eye of him with an evil eye pounces on his bread; And there is turmoil at his table" (Sir 14:10).
The verdict is graded at its highest pitch in Sirach 31: "Remember that an evil eye is an evil thing; God has created nothing more evil than the [evil] eye, Therefore it weeps because of all things" (Sir 31:13). The bracketed [evil] is UPDV's editorial supply; the wording stands as the sage's superlative within the wisdom-comparison register.
The Winking Eye
The eye also signals. The wink is treated as a small, deliberate gesture of malice. "Don't let those who are my enemies wrongfully rejoice over me; Neither let them wink with the eye who hate me without a cause" (Ps 35:19). It is one signal in a roster of mischief-signals: "Who winks with his eyes, who speaks with his feet, Who makes signs with his fingers" (Pr 6:13). It carries its own consequence: "He who winks with the eye causes sorrow; But a prating fool will fall" (Pr 10:10). And it betrays an inner plan: "He who winks with his eye plans evil things, And he who knows him keeps far from him" (Sir 27:22).
The Eyes of Yahweh
Against the human eye, with all its hazards, Scripture sets the eye of Yahweh — figural, anthropomorphic, but graded at maximum. The sage gives the figure its widest measurement: "And he does not perceive that the eyes of the Lord Are ten thousand times brighter than the sun, Beholding all the ways of men, And looking into secret places" (Sir 23:19). Its scope is without remainder: "The works of all flesh are before him, And there is nothing hid from before his eyes" (Sir 39:19), and its span is without limit: "From everlasting to everlasting he beholds, Therefore there is no limit to his salvation" (Sir 39:20).
The Psalter and prophets keep the figure on the righteous and the fearful. "Look, the eye of Yahweh is on those who fear him, On those who hope in his loving-kindness; To deliver their soul from death, And to keep them alive in famine" (Ps 33:18-19). "The eyes of Yahweh are toward the righteous, And his ears are [open] to their cry" (Ps 34:15). The same faculty extends as protection: "The eyes of the Lord are upon those who love him, A mighty protection and a strong stay, A shelter from the scorching wind, a shelter from the midday sun, A guard from stumbling, a help from falling" (Sir 34:19). Paired with the eye-of-Yahweh figure is the keeper-figure who does not sleep: "He will not allow your foot to be moved: He who keeps you will not slumber. Look, he who keeps Israel Will neither slumber nor sleep. Yahweh is your keeper: Yahweh is your shade on your right hand" (Ps 121:3-5).
The apostolic letter restates the figure: "For the eyes of the Lord are on the righteous, And his ears to their supplication: But the face of the Lord is on those who do evil" (1Pe 3:12).
The same divine eye, turned toward judgment, is exhibited at Hab 1:13: "You who are of purer eyes than to look at evil, and who cannot look at perverseness, why do you look on betrayers, and hold your peace when the wicked swallows up the man who is more righteous than he." And at Am 9:8: "Look, the eyes of the Sovereign Yahweh are on the sinful kingdom, and I will destroy it from off the face of the earth; except that I will not completely destroy the house of Jacob, says Yahweh."
Eyes Hidden, Glory Provoked
The same figure has a counter-mode: the divine eye averted, or the divine eye provoked. To hands full of blood, Yahweh says, "And when you⁺ spread forth your⁺ hands, I will hide my eyes from you⁺; yes, when you⁺ make many prayers, I will not hear: your⁺ hands are full of blood" (Isa 1:15). And of Jerusalem and Judah: "their tongue and their doings are against Yahweh, to provoke the eyes of his glory" (Isa 3:8).
Eyes Opened by God
The eye is also something God can open. Hagar in the wilderness sees the spring she could not see: "And God opened her eyes, and she saw a well of water" (Ge 21:19). Balaam sees the angel standing in his road: "Then Yahweh opened the eyes of Balaam, and he saw the angel of Yahweh standing in the way, with his sword drawn in his hand; and he bowed his head, and fell on his face" (Nu 22:31). Elisha's servant sees the unseen host: "And Elisha prayed, and said, Yahweh, I pray you, open his eyes, that he may see. And Yahweh opened the eyes of the young man; and he saw: and, look, the mountain was full of horses and chariots of fire round about Elisha" (2Ki 6:17).
