A.T. Robertson Commentary John 6:50

"This is the bread which cometh down out of heaven, that a man may eat thereof, and not die." — John 6:50 (ASV)

That a man may eat thereof, and not die (ινα τις εξ αυτου φαγη κα μη αποθανη). Purpose clause with ινα and the second aorist active subjunctive of εσθιω and αποθνησκω. The wonder and the glory of it all, but quite beyond the insight of this motley crowd.
