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.'"

 It is little wonder that the disciples found the discourse of Jesus hard. The Greek word is skleros ( G4642) , which means not hard to understand; but hard to accept. The disciples knew quite well that Jesus had been claiming to be the very life of God come down from heaven, and that no one could live this life or face eternity without submitting to him.
