Deut 8:2 And you shall remember that the Lord your God led you all the way these forty years in the wilderness, to humble you and test you, to know what was in your heart, whether you would keep His commandments or not. 3 So He humbled you, allowed you to hunger, and fed you with manna which you did not know nor did your fathers know, that He might make you know that man shall not live by bread alone; but man lives by every word that proceeds from the mouth of the Lord. 4 Your garments did not wear out on you, nor did your foot swell these forty years. 5 You should know in your heart that as a man chastens his son, so the Lord your God chastens you.
Matthew 4:4 But He answered and said, “It is written, ‘Man shall not live by bread alone, but by every word that proceeds from the mouth of God.’”[a]
John 6:6 New King James Version (NKJV)
Feeding the Five Thousand
6 After these things Jesus went over the Sea of Galilee, which is the Sea of Tiberias. 2 Then a great multitude followed Him, because they saw His signs which He performed on those who were diseased. 3 And Jesus went up on the mountain, and there He sat with His disciples.
4 Now the Passover, a feast of the Jews, was near. 5 Then Jesus lifted up His eyes, and seeing a great multitude coming toward Him, He said to Philip, “Where shall we buy bread, that these may eat?” 6 But this He said to test him, for He Himself knew what He would do.
26 Jesus answered them and said, “Most assuredly, I say to you, you seek Me, not because you saw the signs, but because you ate of the loaves and were filled. 27 Do not labor for the food which perishes, but for the food which endures to everlasting life, which the Son of Man will give you, because God the Father has set His seal on Him.”
32 Then Jesus said to them, “Most assuredly, I say to you, Moses did not give you the bread from heaven, but My Father gives you the true bread from heaven. 33 For the bread of God is He who comes down from heaven and gives life to the world.”
42 And they said, “Is not this Jesus, the son of Joseph, whose father and mother we know? How is it then that He says, ‘I have come down from heaven’?”
43 Jesus therefore answered and said to them, “Do not murmur among yourselves. 44 No one can come to Me unless the Father who sent Me draws him; and I will raise him up at the last day. 45 It is written in the prophets, ‘And they shall all be taught by God.’[e]
8 I am the bread of life. 49 Your fathers ate the manna in the wilderness, and are dead. 50 This is the bread which comes down from heaven, that one may eat of it and not die. 51 I am the living bread which came down from heaven. If anyone eats of this bread, he will live forever; and the bread that I shall give is My flesh, which I shall give for the life of the world.”
3 Then Jesus said to them, “Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you. 54 Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day. 55 For My flesh is food indeed,[h] and My blood is drink indeed. 56 He who eats My flesh and drinks My blood abides in Me, and I in him. 57 As the living Father sent Me, and I live because of the Father, so he who feeds on Me will live because of Me. 58 This is the bread which came down from heaven—not as your fathers ate the manna, and are dead. He who eats this bread will live forever.”
61 When Jesus knew in Himself that His disciples complained about this, He said to them, “Does this offend you? 62 What then if you should see the Son of Man ascend where He was before? 63 It is the Spirit who gives life; the flesh profits nothing. The words that I speak to you are spirit, and they are life
