In Hebrew idiom, Good and Evil means all things. What is spoken of is not absolute omniscience such as God alone has; but an unfolding omniscience whereby, without God's direction, man acquires an ever increasing capacity to destroy himself.
Ge 31:24
24 And God came to Laban the Syrian in a dream by night, and said unto him, Take heed that thou speak not to Jacob either good or bad.
KJV
Here the idiom is negated. Laban is told not to say anything to Jacob i.e. Don't try to influence him or turn him back.
