A — 1: κωλύω
(Strong's #2967 — Verb — koluo — ko-loo'-o )

"to hinder, restrain, withhold, forbid" (akin to kolos, "docked, lopped, clipped"), is most usually translated "to forbid," often an inferior rendering to that of hindering or restraining, e.g., 1—Thessalonians 2:16; Luke 23:2; 2—Peter 2:16 , where the RV has "stayed;" in Acts 10:47 "forbid." In Luke 6:29 , the RV has "withhold not (thy coat also)." See HINDER , KEEP , Note (7), STAY , SUFFER , A, Note (3), WITHHOLD , WITHSTAND , No. 1.

"without hindrance" (a, negative, and A, No. 1, is translated "none forbidding him," in Acts 28:31 . From the 2nd century A.D. onwards the word is found constantly in legal documents (Moulton and Milligan, Vocab., who draw attention to the triumphant note on which the word brings the Acts to a close).
