Psalm 78:23-29 New Revised Standard Version (NRSV)
23 Yet he commanded the skies above,
and opened the doors of heaven;
24 he rained down on them manna to eat,
and gave them the grain of heaven.
25 Mortals ate of the bread of angels;
he sent them food in abundance.
26 He caused the east wind to blow in the heavens,
and by his power he led out the south wind;
27 he rained flesh upon them like dust,
winged birds like the sand of the seas;
28 he let them fall within their camp,
all around their dwellings.
29 And they ate and were well filled,
for he gave them what they craved.
John 6:24-38 New Revised Standard Version (NRSV)
24 So when the crowd saw that neither Jesus nor his disciples were there, they themselves got into the boats and went to Capernaum looking for Jesus.
25 When they found him on the other side of the sea, they said to him, “Rabbi, when did you come here?” 26 Jesus answered them, “Very truly, I tell you, you are looking for me, not because you saw signs, but because you ate your fill of the loaves. 27 Do not work for the food that perishes, but for the food that endures for eternal life, which the Son of Man will give you. For it is on him that God the Father has set his seal.” 28 Then they said to him, “What must we do to perform the works of God?” 29 Jesus answered them, “This is the work of God, that you believe in him whom he has sent.” 30 So they said to him, “What sign are you going to give us then, so that we may see it and believe you? What work are you performing? 31 Our ancestors ate the manna in the wilderness; as it is written, ‘He gave them bread from heaven to eat.’” 32 Then Jesus said to them, “Very truly, I tell you, it was not Moses who gave you the bread from heaven, but it is my Father who gives you the true bread from heaven. 33 For the bread of God is that which comes down from heaven and gives life to the world.” 34 They said to him, “Sir, give us this bread always.”
35 Jesus said to them, “I am the bread of life. Whoever comes to me will never be hungry, and whoever believes in me will never be thirsty. 36 But I said to you that you have seen me and yet do not believe. 37 Everything that the Father gives me will come to me, and anyone who comes to me I will never drive away; 38 for I have come down from heaven, not to do my own will, but the will of him who sent me.
