Greek for piety. See the page on eusebeia to learn more about what it means to be pious in Hellenismos.

Eusebeia (Greek:εὐσέβεια, from eu meaning "well", and sebomai meaning "reverence", itself formed from seb meaning sacred awe and reverence especially in actions) is a Greek word abundantly used in Greek philosophy as well as in the New Testament, meaning inner piety, spiritual maturity, or godliness.
