χωριζέτω [2 verses](verb 3rd sg pres imperat act) "Put asunder" is chorizo which means "separate," "divide," "exclude," "separate in thought," "distinguish," and, in the passive, "to be separated," "severed," "divided," "to be different," "depart," and "to go away.  - The word translated as "put asunder" means to physically "separate," or "divide," but is also means to "separate in thought," and "distinguish." Jesus only uses this word here and in the parallel verse in Mark. Everywhere else he uses another word to mean "divide" in the sense of severing. We assume this is because of the "separate in thought" meaning.
