Limited to Mt. 10:21; 26:59; 27:1; Mk. 13:12; 14:55; Lk. 21:16; Rom. 7:4; 8:13, 36; 2 Cor. 6:9; 1 Pet. 3:18, the Greek verb “thanatoo” meant “kill” or “put to death.”  Every time this word is used in the New Testament, man is the instigator of this act.  This action most often describes the physical destruction of life, but Rom. 8:13 talk about “killing” the works of the flesh.
