Exod 16:2-4, 12-15
 And all the congregation of the children of Israel murmured against Moses and Aaron in the wilderness.  And the children of Israel said to them: Would to God we had died by the hand of the Lord in the land of Egypt, when we sat over the flesh pots, and ate bread to the full. Why have you brought us into this desert, that you might destroy all the multitude with famine?  And the Lord said to Moses: Behold I will rain bread from heaven for you: let the people go forth, and gather what is sufficient for every day: that I may prove them whether they will walk in my law, or not.  I have heard the murmuring of the children of Israel: say to them: In the evening you shall eat flesh, and in the morning you shall have your fill of bread: and you shall know that I am the Lord your God.  So it came to pass in the evening, that quails coming up, covered the camp: and in the morning, a dew lay round about the camp.  And when it had covered the face of the earth, it appeared in the wilderness small, and as it were beaten with a pestle, like unto the hoar frost on the ground.  And when the children of Israel saw it, they said one to another: Manhu! which signifieth: What is this! for they knew not what it was. And Moses said to them: This is the bread, which the Lord hath given you to eat.
Eph 4:17, 20-24
 This then I say and testify in the Lord: That henceforward you walk not as also the Gentiles walk in the vanity of their mind,  But you have not so learned Christ;
 If so be that you have heard him, and have been taught in him, as the truth is in Jesus:  To put off, according to former conversation, the old man, who is corrupted according to the desire of error.  And be renewed in the spirit of your mind:  And put on the new man, who according to God is created in justice and holiness of truth.
 When therefore the multitude saw that Jesus was not there, nor his disciples, they took shipping, and came to Capharnaum, seeking for Jesus.  And when they had found him on the other side of the sea, they said to him: Rabbi, when camest thou hither?
 Jesus answered them, and said: Amen, amen I say to you, you seek me, not because you have seen miracles, but because you did eat of the loaves, and were filled.  Labour not for the meat which perisheth, but for that which endureth unto life everlasting, which the Son of man will give you. For him hath God, the Father, sealed.  They said therefore unto him: What shall we do, that we may work the works of God?  Jesus answered, and said to them: This is the work of God, that you believe in him whom he hath sent.  They said therefore to him: What sign therefore dost thou shew, that we may see, and may believe thee? What dost thou work?
 Our fathers did eat manna in the desert, as it is written: He gave them bread from heaven to eat.  Then Jesus said to them: Amen, amen I say to you; Moses gave you not bread from heaven, but my Father giveth you the true bread from heaven.  For the bread of God is that which cometh down from heaven, and giveth life to the world.  They said therefore unto him: Lord, give us always this bread.  And Jesus said to them: I am the bread of life: he that cometh to me shall not hunger: and he that believeth in me shall never thirst.
