“What and if yee shall see the sonne of man ascend vp where hee was before?”
1611 King James Version (KJV)
6:62 What if ye shall see the Son of man ascend where he was before? - How much more incredible will it then appear to you, that he should give you his flesh to eat?
Joh 6:62 [What] if ye shall see the Son of man ascend? He points forward to a greater marvel than the one that now staggered before them, the Ascension of the Son of man.
