I think wideawake may be looking at the word for Devour such as in Hebrews 10:27 (but a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.) which is also esthio but is preceded by phago which, together is used in the same context as a different word trogo which does mean, as wide awake stated, to literally gnaw. John 6:53, however, doesn't use either trogo nor phago esthio, just esthio.

No, that is esthio.

a different word trogo which does mean, as wide awake stated, to literally gnaw

That is an even more intense word, which continues the aggressiveness of the language used in the passage, starting in 6:54 - to rip with the teeth.

John 6:53, however, doesn't use either trogo nor phago esthio, just esthio.

Again, I have to disagree.
