Enoch (Cain's son)

"Knew his wife" preserves the Hebrew verb yadaʿ ("to know") exactly as it stands. It is a well-known biblical euphemism for sexual union, and plainer renderings such as "had relations with" or "lay with" are possible; but the literal wording has been kept because it reads with dignity aloud and because the same idiom recurs throughout these chapters (compare 4:1, 4:25). The second half of the verse is compressed in Hebrew: literally "and he was building a city, and he called the name of the city like the name of his son, Enoch." "Cain" has been supplied as the subject of "was building" for clarity in reading aloud, since Hebrew leaves the pronoun unexpressed and a reader could momentarily attach it to Enoch. "He named it after his son Enoch" renders the fuller Hebrew phrase idiomatically rather than word for word.

The clause wayhî bōneh ("he was building") uses a participle with the verb "to be," a construction that expresses ongoing or repeated action rather than a single completed act — the sense is that Cain was engaged in the work of city-building. The name Enoch (Ḥanôk) is related to the root ḥanak, "to dedicate, initiate, train," the same root behind the word for the dedication of a building or altar. There is thus a quiet wordplay: the founder dedicates his city with a name that itself means "dedication." Hebrew ʿîr ("city") covers anything from a walled settlement to a modest fortified enclosure, and need not imply a large urban center.

The identity of Cain's wife is not stated, and the narrative shows no interest in the question. Ancient Jewish tradition generally assumed she was a sister, since Genesis 5:4 notes that Adam fathered sons and daughters; some later writings even supply her with a name. The text's silence suggests the narrator is tracing lines of descent and culture rather than answering questions of population.

City-building in the ancient Near East was a prestigious act, often credited in Mesopotamian tradition to gods, kings, or primeval heroes. Genesis assigns it instead to Cain's line, which in the following verses is also credited with herding, music, and metalworking — the foundations of civilization emerging from the family of the first murderer. Archaeologically, walled settlements in the region are very old, and the note fits a world in which a "city" could be a small fortified cluster of dwellings.

There is a pointed irony here: the man sentenced to be a restless wanderer (4:12) settles down and builds a walled city, seeking by his own effort the security God had already promised him by a mark of protection. Interpreters have read this in two directions. Some see defiance — human self-protection substituted for divine keeping, the city as a monument to a name Cain wants remembered. Others see God's common grace, allowing culture, craft, and community to flourish even in a cursed line. The naming of the city after his son also raises the theme of legacy: Cain builds and names, while it is Seth's line that will "call on the name of the LORD" (4:26).

The verse is stable across the manuscript tradition; the ancient versions all agree with the received Hebrew text, differing only in the transliteration of the name Enoch. Some early interpreters, troubled by the sequence, took Enoch rather than Cain as the builder — an alternative supported by no textual variant, only by reading the unexpressed subject differently.

The verse opens with a passive verb form, literally "and there was born to Enoch Irad," which the translation preserves as "To Enoch was born Irad." The remaining links use the active verb "begot/fathered," rendered here as "was the father of" for smoother oral delivery; the older "begat" carries the same sense but is archaic when read aloud. The repeated pattern of name-plus-verb is kept intentionally, since the chain-like repetition is the point of a genealogy and gives the sentence its rhythm when spoken.

The verb ילד (yalad) means "to bear, bring forth"; in the passive stem it describes the child being born, in the causative/active stem the parent's role in producing offspring. Hebrew uses the same root for both mother and father, so "fathered" is an interpretive narrowing that the context requires. The names themselves are compact sentences or descriptions: Mehujael and Methushael both end in -el, "God," and Methushael likely echoes an old Semitic form meaning "man of God"; Mehujael has been read either as "struck by God" or "God gives life," and Irad's meaning remains uncertain, possibly connected to a word for "wild donkey" or to a city name.

Within this single verse the same person's name is written two different ways in the Hebrew consonantal text: first Mehuyael, then Mehiyyael. Ancient versions and some manuscripts smooth this out to one spelling, and the translation likewise uses a single form so the listener is not confused into hearing two people. Some witnesses also read the opening verb as active, "Enoch fathered Irad," matching the pattern of the rest of the verse rather than the passive of the received Hebrew text.

Genealogies functioned in the ancient world as charters of identity, tracing craft, land and clan rather than merely satisfying curiosity about ancestry. This seven-generation line from Adam through Cain to Lamech's sons is structured to reach a climax in the following verses, where the origins of herding, music and metalwork are traced to Lamech's children. Names of this type, several with Mesopotamian resonance, suggest the list preserves very old traditional material.

The names in Cain's line closely resemble those in Seth's line in the next chapter: Enoch, Irad, Mehujael, Methushael and Lamech stand alongside Enoch, Jared, Mahalalel, Methuselah and Lamech. Interpreters differ on whether these are two versions of one tradition or two deliberately paired lines meant to be compared — the one culminating in Lamech's song of vengeance, the other in Enoch who walked with God and in Noah. Read as a pair, they set two trajectories of human history side by side without yet pronouncing judgment on either.
