Hebrews 6:4-6

ASV(i) 4 For as touching those who were once enlightened and tasted of the heavenly gift, and were made partakers of the Holy Spirit, 5 and tasted the good word of God, and the powers of the age to come, 6 and [then] fell away, it is impossible to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.
