Hebrews 12:17-19

12:17 For you know that later when he wanted to inherit the blessing, he was rejected, for he found no opportunity for repentance, although he sought the blessing with tears. 12:18 For you have not come to something that can be touched, to a burning fire and darkness and gloom and a whirlwind 12:19 and the blast of a trumpet and a voice uttering words such that those who heard begged to hear no more.
