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.'"
Verily, verily, I say unto you, Except you eat the flesh of the Son of man, and drink his blood, you have no life in you ( John 6:53 ).
