John 6:30-36

So they said to Him, “What sign (attesting miracle) will You do that we may see it and believe You? What [supernatural] work will You do [as proof]? Our fathers ate the manna in the wilderness; as it is written [in Scripture], ‘HE GAVE THEM BREAD OUT OF HEAVEN TO EAT.’ ” [Ex 16:15; Neh 9:15; Ps 78:24] Then Jesus said to them, “I assure you and most solemnly say to you, it is not Moses who has given you the bread out of heaven, but it is My Father who gives you the true bread out of heaven. For the Bread of God is He who comes down out of heaven, and gives life to the world.” Then they said to Him, “Lord, always give us this bread.” Jesus replied to them, “I am the Bread of Life. The one who comes to Me will never be hungry, and the one who believes in Me [as Savior] will never be thirsty [for that one will be sustained spiritually]. But as I told you, you have seen Me and still you do not believe.
