primarily, dedicated to the gods, sacred (Hdt.; rare in Att., never in Hom., Hes. and Trag., who use ἁγνός), hence, holy, characteristic of God, separated to God, worthy of veneration.

__2. Applied to persons as separated to God's service:
__(a) of Christ, Mrk.1:24, Jhn.6:69, Act.4:30;
__(b) of Christians, Act.9:13, Rom.1:7, Heb.6:10, Rev.5:8.
