68.48 · Aspect · Cease, Stop
to stop completely, to cease completely (a figurative extension of meaning of θανατόω[a] ‘to put to death,’ 20.65) to cease completely from activity, with the implication of extreme measures taken to guarantee such a cessation It is possible that in rendering this expression in ROM 8:13 one may desire to retain the figure of speech and therefore translate ‘if by the Spirit you put to death the works of the body.’
1 In certain instances, particularly in the case of θανατόω[b] and νεκρόω, it is difficult to determine whether the figurative meanings involved have become conventionalized or whether they represent what may be called figurative usage, in other words, new figures of speech which no doubt had become somewhat conventional for the Christian community.
