'Knowing' in the Bible

For God knows that on the day you [both] eat from it, then your eyes will be opened and you [both] shall be like gods, knowing good and evil."

Then Huram said, "Blessed be Yahweh, the God of Israel, who has made the heavens and the earth, who has given to King David a wise son knowing discretion and understanding, who will build for Yahweh a house and a royal palace for himself.

So do the wise [really] have an advantage over fools? {Can the poor [really] gain anything by knowing how to act in front of others}?
