The lemma δικαιοσύνη normally refers to righteousness, justice, or rightness, and the lexicon artifact also ties it to equity of character or act.

The genitive links righteousness to the preceding noun of showing, so the clause speaks of a demonstration or disclosure of that righteousness rather than merely naming it in isolation.
