A.T. Robertson Commentary John 6:35

"Jesus said unto them. I am the bread of life: he that cometh to me shall not hunger, and he that believeth on me shall never thirst." — John 6:35 (ASV)

I am the bread of life (Εγω ειμ ο αρτος της ζωης). This sublime sentence was startling in the extreme to the crowd. Philo does compare the manna to the θειος λογος in an allegorical sense, but this language is far removed from Philo's vagueness. In the Synoptics (Matthew 26:26; Luke 22:19) Jesus uses bread (αρτος) as the symbol of his body in the Lord's Supper, but here Jesus offers himself in place of the loaves and fishes which they had come to seek (24,26). He is the bread of life in two senses: it has life in itself, the living bread (51), and it gives life to others like the water of life, the tree of life. John often has Jesus saying "I am" (εγω ειμ). As also in 6:41,48,51; 8:12; 10:7,9,11,14; 11:25; 14:6; 15:1,5.

He that cometh to me (ο ερχομενος προς εμε). The first act of the soul in approaching Jesus. See also verse 37.

Shall not hunger (ου μη πειναση). Strong double negative ου με with first aorist (ingressive) active subjunctive, "shall not become hungry."

He that believeth on me (ο πιστευων εις εμε). The continuous relation of trust after coming like πιστευητε (present tense) in verse 29. See both verbs used together also in 7:37f.

Shall never thirst (ου μη διψησε πωποτε). So the old MSS. the future active indicative instead of the aorist subjunctive as above, an even stronger form of negation with πωποτε (1:18) added.
