Limited to Mt. 9:2, 22; 14:27; Mk. 6:50; 10:49; Lk. 8:48 (some manuscripts); Jn. 16:33; Acts 23:11, the Greek verb “tharseo,” which is always used in the imperative mood, meant confident,” “to be cheerful,” “unafraid.”  This term is often associated with miracles.  In Jn. 16:33, this verb exhorted the disciples to never give up; they were to be bold and have courage because Jesus had “overcome the world.”  Compare Luke’s use of this term in Acts 23:11.
