στηριγμός

βεβαίωσις bebaíōsis · G951 · to confirm, to verify, to prove to be true and certain

Greek βεβαίωσις denotes the act or state of making firm/stable, confirmation, closely paralleling στηριγμός as firmness or stability (especially in a figurative sense of being established securely).

ἀσφάλεια aspháleia · G803 · safety, security, certainty

Greek ἀσφάλεια denotes security, safety, or certainty (a state of being secure/stable), overlapping with στηριγμός in the sense of a firm, safe position or stability.

Place of safety, position of safety21.13

The noun names a secure position from which one might fall. Peter warns, “be on your guard so that you are not carried away by the error of unscrupulous people and lose your own firm commitment” (2 Peter 3:17).

Firm position, being firm in, firmness, steadfastness74.20

The same noun, in the same warning, also carries the nuance of a settled, stable condition of conviction—since this is the lexeme's only tagged occurrence, the same phrase pictures both a secure standing and an inward firmness. Peter continues, “be on your guard so that you are not carried away by the error of unscrupulous people and lose your own firm commitment” (2 Peter 3:17).

Words formed from the same root. They share a form, not always a meaning.
