Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
Whosoever, х Pas (G3956) ho (G3588)] - 'Everyone who,' etc.
Committeth sin - in contrast to 1 John 3:3, "every man that hath this hope in him purifieth himself" (cf. 1 John 3:7).
Transgresseth also the law, х poiei (G4160) teen (G3588) anomian (G458)] - 'committeth transgression of law.' God's law of purity; so shows he has no such hope of being hereafter pure as God is pure; therefore, that he is not born of God.
For, х kai (G2532)] - 'and.'
Sin is the transgression of the law - definition of sin. The Greek ('Aleph (') A C; but B х hamartia (G266)], without he) having the article to both, implies they are convertible terms. "Sin" х hamartia (G266)] is a missing of the mark, God's will to be ever aimed at. (Romans 3:20, "By the law as the knowledge of sin.") The crookedness of a line is shown by juxtaposition with a straight ruler.
