John 6:20-30

23 However, boats from Tiber'i-as came near the place where they ate the bread after the Lord had given thanks.
24 So when the people saw that Jesus was not there, nor his disciples, they themselves got into the boats and went to Caper'na-um, seeking 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, "Truly, truly, I say to you, you seek me, not because you saw signs, but because you ate your fill of the loaves.
27 Do not labor for the food which perishes, but for the food which endures to eternal life, which the Son of man will give to you; for on him has God the Father set his seal."
28 Then they said to him, "What must we do, to be doing 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, "Then what sign do you do, that we may see, and believe you? What work do you perform?
