Adder

The adder appears in the UPDV as a venomous serpent of the path, the wall, and the den — a low-set, fang-bearing creature whose bite is sudden and whose poison is the standing measure for everything deadly. Across narrative, psalter, wisdom, and prophet, the adder is invoked literally as a hazard of the terrain and figuratively as the likeness of wicked speech, of wine's hidden end, and, in reverse, of the threat that Yahweh's sheltered ones tread underfoot.

The Adder of the Path

Jacob's oracle on Dan plants the adder along the traveler's road as the ambush-creature whose strike topples a mounted man: "Dan will be a serpent in the way, An adder in the path, That bites the horse's heels, So that his rider falls backward" (Gen 49:17). The adder is set low in the path; the heel-bite targets the horse, and the falling-backward clause ejects the rider. The serpent and the adder stand in parallel — one tribe likened to both at once — fixed at the wayside as the venom-creature whose strike unhorses whoever passes.

Poison Under the Lips

David twice diagnoses wicked speech by the adder's venom. On the evil and violent men of Psalm 140, he lays the figure across both the speaking organ and its hidden reservoir: "They have sharpened their tongue like a serpent; Adders' poison is under their lips. Selah" (Ps 140:3). The tongue is honed at serpent-fang register; the lips conceal a standing pool of adders' venom; each utterance issues out of a poison-gland.

The companion psalm widens the figure to the whole person. Of the wicked class of Psalm 58, "Their poison is like the poison of a serpent: [They are] like the deaf cobra that stops her ear" (Ps 58:4). The cobra here is the adder-kind; its qualifying trait is the deafness that blocks the charmer's voice, so the wicked are not only venomous in content but incorrigible at the ear.

Paul carries the same image into the indictment of Romans 3, where the asp — the adder-class — is named again as the source of a hidden lethality lodged at the site of speech: "Their throat is an open tomb; With their tongues they have used deceit: The poison of asps is under their lips" (Rom 3:13). The Davidic figure of pooled venom beneath the lips is enlisted as one of the catena's witnesses against humanity.

The Cup that Bites at the End

The sage applies the adder-figure to wine's after-effect. The fourth strophe of Proverbs 23 watches the cup sparkle and then turns the camera on what the cup becomes once it is drunk: "At the last it bites like a serpent, And stings like an adder" (Pr 23:32). The "at the last" temporal phrase fastens the figure not on the wine's appearance but on its closing effect; the parallel movement steps from the general serpent's bite to the specific adder's sting, so the after-the-cup poisoning of the body is graded at venom-injection register. Zophar applies a kindred figure to the wicked man's gain: "He will suck the poison of cobras: The viper's tongue will slay him" (Job 20:16). What the sage warns the wine-drinker against, Zophar reports as already happening to the wicked who feeds on his wickedness: he draws cobra-venom in as his own drink. Moses' Song reaches the same register from another side, applying the figure to the enemies' wine itself: "Their wine is the poison of serpents, And the cruel venom of cobras" (Deut 32:33).

Trodden Underfoot

The adder is also that which the sheltered worshipper subdues. To the one who has made the Most High his habitation, the psalmist promises a beast-victory at twin register: "You will tread on the lion and cobra: The young lion and the serpent you will trample under foot" (Ps 91:13). The cobra-adder is paired with the lion so that the chief venom-threat and the chief fang-threat fall together; the tread / trample verb-pair fastens the subjugation at foot-crushing register.

The Hand at the Adder's Den

Isaiah lifts the figure into messianic peace. In the holy mountain that does not hurt nor destroy, the snake-den itself is turned into a play-site: "And the nursing child will play on the hole of the cobra, and the weaned child will put his hand on the adder's den" (Isa 11:8). The cobra and the adder are paired as the venom-snakes whose striking-power is exhibited as nullified — small children handle the very mouths of their burrows without harm. The terror that Genesis 49 set on the path and that Proverbs 23 tasted at the end of the cup is, in this oracle, disarmed at its own door.
