I wot that he whom thou blessest is blessed, and he whom thou cursest is cursed. This was the language of flattery intended to secure the prophet's services. No doubt, however, Balak, like other heathens, had a profound though capricious belief in the real effect of curses and anathemas pronounced by men who had private intercourse and influence with the unseen powers.
That error, like most superstitions, was the perversion of a truth; there are both benedictions and censures which, uttered by human lips, carry with them the sanction and enforcement of Heaven. The error of antiquity lay in ignorance or forgetfulness that, as water cannot rise higher than its source, so neither blessing nor cursing can possibly take any effect beyond the will and purpose of the Father of our souls.
Balaam knew this, but it was perhaps his misfortune to have been trained from childhood to maintain his position and his wealth by trading upon the superstitions of his neighbours.
