Our fathers ate the manna in the wilderness. As it is written, 'He gave them bread out of heaven{Greek and Hebrew use the same word for "heaven", "the heavens", "the sky", and "the air".} to eat.'"

 6:51b-59 "The bread which I will give him is my flesh, which is given that the world may have life." So the Jews argued with each other. "How" they said, "can this man give us his flesh to eat?" Jesus said to them: "This is the truth I tell you--unless you eat the flesh of the Son of Man and drink his blood, you cannot possess eternal life within yourselves. He who eats my flesh and drinks my blood has eternal life, and I will raise him up on the last day. My flesh is the real food and my blood is the real drink. He who eats my flesh and drinks my blood remains in me and I in him. As the living Father has sent me, so I live through him; and he who eats me will live through me. This is the bread which came down from heaven. It is not a case of eating, as your fathers ate and died. He who eats this bread lives for ever." He said these things when he was teaching in the synagogue at Capernaum.
