Transgression is willful, deliberate rebellion against a known law or covenant. Unlike chattah (missing the mark by mistake) or avon (inward perversity), pesha carries the idea of open defiance — a conscious stepping over a clearly drawn boundary. David confesses "my transgressions" as distinct from his sin and iniquity (Ps 51:1–3), showing Scripture's nuanced vocabulary of wrongdoing. Isaiah 53:5 declares that "he was wounded for our transgressions" — the servant bearing the cost of our willful revolt. The good news is that God forgives and covers transgressions (Ps 32:1; Micah 7:18–19).
TRANSGRESSION, n. [L. transgressio.] The act of passing over or beyond any law or rule of moral duty; the violation of a law or known principle of rectitude; fault; offense; crime; sin. Every sin is a transgression of the divine law. Paul: "Where there is no law there is no transgression" (Rom 4:15).
Isaiah 53:5 — "He was pierced for our transgressions; he was crushed for our iniquities."
Psalm 51:1–3 — "Have mercy on me, O God…blot out my transgressions…I know my transgressions, and my sin is ever before me."
Psalm 32:1 — "Blessed is the one whose transgression is forgiven, whose sin is covered."
Romans 4:15 — "Where there is no law there is no transgression."
Micah 7:18 — "Who is a God like you, pardoning iniquity and passing over transgression?"
H6588 — pesha (פֶּשַׁע): rebellion, revolt, transgression; the most intense OT word for sin — a conscious, willful breaking of relationship with God or man.

G3845 — parabainō (παραβαίνω): to step beside, transgress; root verb of parabasis.
• "Sin is missing the mark; iniquity is the bent nature within; transgression is the open revolt."
• "The cross is the only place where the penalty for deliberate rebellion has been fully absorbed."
• "David's Psalm 51 models the courage required to name pesha — not merely 'mistakes' but willful defiance."
Modern culture has largely abandoned the concept of transgression because it requires a fixed law to transgress. When morality is reduced to personal preference or cultural consensus, there is no line to cross — only choices to be made. Even in the church, "transgression" language has been softened to "mistake" or "struggle," removing the element of willful choice and accountability. Scripture is not so gentle: to transgress is to know the line and cross it anyway. This is why confession of pesha is so weighty in the Psalms — it is an admission of deliberate rebellion, not accidental failure.
