John 6:58

This is that bread which came down from heaven
That true bread, the bread of God, the bread of life, living bread; meaning himself, as in ( John 6:32 John 6:33 John 6:35 John 6:48 John 6:50 John 6:51 ) ;

not as your fathers did eat manna, and are dead:
this is bread of a quite different nature from that; that was only typical bread, this true; that was the bread of angels, but this is the bread of God; that came but from the air, this from the third heaven; that men ate of, and died; but whoever eats of this, lives for ever; see ( John 6:49 ) ; as follows:

he that eateth of this bread shall live for ever;
(See Gill on John 6:51).
