John 6:29-31

Amplified Bible

²⁹ Jesus answered, “This is the work of God: that you believe [adhere to, trust in, rely on, and have faith] in the One whom He has sent.” ³⁰ 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]? ³¹ Our fathers ate the manna in the wilderness; as it is written [in Scripture], ‘He gave them bread out of heaven to eat.’”^(A)
