His  disciples,  concerning  those  false  teachers  who,  under
the  guise  of  His  sheep,  should  in  later  days,  steal  into  the
fold,  and  strive  to  make  void  the  doctrine  which  He  had

should  arise  ;'  it  is  your  business  to  guard  against  the  harm
which  they  may  work.
For  this  purpose,  there  is  need  of  much  watchfulness  ;

of  light,  so  are  these,  his  agents,  able  to  carry  a  smooth  ex
terior   and  wear  all  the  semblance  of  great  virtue.     Their
company  is  often  most  attractive  ;  their  conversation  and
bearing  are  agreeable  ;  companions  gather  round  them,  go
frequently   with   them,    and   become   their   bosom    friends.
