Hebrews 6:6

Hebrews 6:6 AMPC

If they then deviate from the faith and turn away from their allegiance–[it is impossible] to bring them back to repentance, for (because, while, as long as) they nail upon the cross the Son of God afresh [as far as they are concerned] and are holding [Him] up to contempt and shame and public disgrace.
