Heb 3:15-19
15 These words keep ringing in our ears:
Today, please listen; don't turn a deaf ear as in the bitter uprising.
16 For who were the people who turned a deaf ear? Weren't they the very ones Moses led out of Egypt? 17 And who was God provoked with for forty years? Wasn't it those who turned a deaf ear and ended up corpses in the wilderness? 18 And when he swore that they'd never get where they were going, wasn't he talking to the ones who turned a deaf ear? 19 They never got there because they never listened, never believed.

I HAVE NEVER HEARD A SERMON ON THIS!
