John 6:26-28

²⁶Jesus answered them and said, Verily, verily, I say to you, Ye seek me, not because ye saw the miracles, but because ye ate of the loaves, and were satisfied.

²⁷Labor not for the food which perisheth, but for that food which endureth to everlasting life, which the Son of man will give to you: for him hath God the Father sealed.

²⁸Then said they to him, What shall we do, that we may work the works of God?
