{Lead you astray} (h(966d)(8373) plan(8873)(8869)). This warning runs all
through the discourse. It is amazing how successful deceivers
have been through the ages with their eschatological programs.
The word in the passive appears in  18:12  when the one sheep
wanders astray. Here it is the active voice with the causative
sense to lead astray. Our word planet comes from this root.
