1 John 3:12

Cain who was [κ α ι ν η ν]. Who is not in the Greek. The construction is irregular. Lit., as Rev., not as Cain was of the evil one.

Slew [ε σ φ α ξ ε ν]. The verb occurs only in John, and only here outside of Revelation. Originally, to slay by cutting the throat; so in Homer, of cattle :

"the suitor train who slay [σ φ α ζ ο υ σ ι] His flocks and slow - paced beeves with crooked horns." " Odyssey, " 1, 92.

To slaughter victims for sacrifice :

"Backward they turned the necks of the fat beeves, And cut their throats [ε σ φ α ζ α ν], and flayed the carcasses." " Iliad, " 1, 459.

Thence, generally, to slay or kill.

Wherefore [χ α ρ ι ν τ ι ν ο ς]. Lit., on account of what. Carin for the sake of, on account of, is elsewhere placed after the genitive. See Ephesians 3:1; Ephesians 3:14; 1 Timothy 5:14; Galatians 3:19.
