the seer: The word roaih: literally signifies one who sees; particularly preternatural sights. A seer and a prophet were the same in most cases; only with this difference, the seer was always a prophet, but the prophet was not always a seer. A seer seems to imply one who frequently met with and saw some symbolical representation of God. All prophets, true or false, profess to see God (see Numbers 24:4, Numbers 24:16. Jeremiah 14:4); and diviners, in their enthusiastic flights, boasted that they had those things exhibited to their sight which should come to pass.
