And he said, Go, and tell this people, Hear ye indeed, but understand not; and see ye indeed, but perceive not.
Hear ye indeed, but understand not - Hebrew, In hearing, hear; i:e., Though ye hear the prophet's warnings again and again, ye are doomed, because of your perverse will (John 7:17), not to understand. Light enough is given in Revelation to guide those sincerely seeking to know, in order that they may do, God's will; darkness enough is left to confound the willfully blind (Isaiah 43:8). So in Jesus' use of parables (Matthew 13:14).
See ye indeed - Hebrew, see in seeing; 'though ye see again and again' yet, etc.
