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.'"
And Jesus took the cup and He said, "Take, drink; this is the blood of the new covenant which is shed for the remission of sin" ( Matthew 26:27-28 ). "Eat of My flesh, drink of My blood, partake of Me, that you might have life. For My flesh is meat indeed My blood is drink indeed."
