Genesis 27:12

Summary

Jacob voices his fear that his father Isaac might physically detect the deception (being asked to impersonate Esau) by touching him, which would expose him as a deceiver rather than earn him a blessing. The verse expresses a conditional worry followed by two consequences framed as a sequence of feared outcomes.

Key words

• 'u.Lai ("perhaps", H0194) — an adverb of uncertainty that opens the sentence, signaling Jacob's hesitation rather than a flat prediction.
• ye.mu.She.ni ("he will feel me", H4959) — qal imperfect with 1st-person suffix ni ("me", H9030); the imperfect marks a future/possible action, tied to the initial 'u.Lai to form a conditional "what if" sense.
• ke.mta'.Te.a' ("a mocker", H8591) — piel participle, masculine singular; the piel stem intensifies the action, and the participle form casts Jacob not simply as one who mocks but as one characteristically doing so — the role he fears being assigned in his father's eyes.
• be.'ei.Nav ("in his eyes", H5869I) — construct noun in the dual form (denoting the two eyes) with 3rd-person suffix v ("his", H9023); the idiom situates the feared judgment specifically in Isaac's perception.
• qe.la.Lah ("a curse", H7045) and ve.ra.Khah ("a blessing", H1293) — both feminine singular nouns, placed in direct opposition at the end of the verse via ve...lo' ("and not", H9002/H3808), contrasting the two possible outcomes of the encounter.

What the text says

The verse is built as a chain introduced by 'u.Lai ("perhaps"), governing an imperfect verb (ye.mu.She.ni, "he will feel me") that expresses the feared event. This is followed by two verbs in the sequential perfect form (ha.Yi.ti, "I will be" and he.ve.Ti, "I will bring"), a common Hebrew construction where perfect-form verbs continue a chain of future or hypothetical consequences begun by an initial verb — here the initial uncertainty set by 'u.Lai. Structurally, the verse presents three connected clauses: (1) the feared physical detection, (2) the resulting identification "in his eyes" as ke.mta'.Te.a', and (3) the self-inflicted outcome of curse rather than blessing.

The dual form of 'ei.Nayv ("his eyes") is a fixed grammatical feature of the noun for "eyes" in Hebrew and does not add separate meaning beyond the idiomatic sense of perception or judgment. The final opposition between qe.la.Lah ("curse") and ve.ra.Khah ("blessing") mirrors the broader narrative concern with blessing transmission, framed here as a binary risk rather than a certainty, consistent with the conditional tone set by 'u.Lai.

Differences between versions

The LXX renders the participle ke.mta'.Te.a' ("mocker", H8591) as καταφρονῶν ("one who despises/disdains"), a related but distinct nuance from the Hebrew's connotation of deception or mockery. The Vulgate expands the verse with interpretive additions — "et senserit, timeo ne putet me sibi voluisse illudere" ("and if he perceives it, I fear he may think I wished to mock him") — introducing explicit vocabulary of fear and intention not present as separate lexical items in the Hebrew text, where the sequence is expressed through verb chaining alone rather than an explicit statement of fear.
