A — 1: βέβηλος
(Strong's #952 — Adjective — bebelos — beb'-ay-los )

primarily, "permitted to be trodden, accessible" (from baino, "to go," whence belos, "a threshold"), hence, "unhallowed, profane" (opposite to hieros, "sacred"), is used of (a) persons, 1—Timothy 1:9; Hebrews 12:16; (b) things, 1—Timothy 4:7; 6:20; 2—Timothy 2:16 . "The natural antagonism between the profane and the holy or divine grew into a moral antagonism. ... Accordingly bebelos is that which lacks all relationship or affinity to God" (Cremer, who compares koinos, "common," in the sense of ritual uncleanness).

B — 1: βεβηλόω
(Strong's #953 — Verb — bebeloo — beb-ay-lo'-o )

primarily, "to cross the threshold" (akin to A, which see), hence, "to profane, pollute," occurs in Matthew 12:5; Acts 24:6 (the latter as in Acts 21:28,29 : cp. DEFILE, A, No. 1, PARTITION).
