John 6:26-31

²⁶Jesus 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.

²⁷Do not work for the food that perishes, but for the food that endures to eternal life, which the Son of Man will give to you; for upon Him God the Father has set His seal.”

²⁸Then they said to Him, “What should we do, that we may work the works of God?”

²⁹Jesus answered and said to them, “This is the work of God, that you believe in Him whom He sent.”

³⁰Therefore they said to Him, “What sign will You do then, so that we may see it and believe You? What work do You perform?

³¹Our fathers ate the manna in the wilderness; as it is written, ‘He gave them bread from heaven to eat.’ ”
