“Then saide Iesus againe vnto them, I goe my way, and ye shall seeke me, & shall die in your sinnes: Whither I goe, ye cannot come.”
1611 King James Version (KJV)
Joh 8:21 Whither I go, ye cannot come. Because they shall "die in their sins", and he will return to heaven, where the sinner cannot enter.
