KNOW YOUR ENEMY!!!!.... NEVER Trust thine Enemy: for as like iron rusts,so is his wickedness. Though he humble himself, and go crouching,yet TAKE GOOD HEED AND BE AWARE OF HIM, and thou shall be unto him as if thou has wiped a looking glass,and thou shalt know that his rust has not altogether wiped away. SET HIM NOT BESIDE YOU,LEST HE STAND UP-IN YOUR PLACE/POSITION, NEITHER LET HIM SIT AT YOUR RIGHT HAND, LEST HE SEEK TO TAKE-YOUR SEAT/POSITION/IDENTITY, and thou at the last remember my words, and be pricked therewith. SIRACH 12:10-12
