John 6:26-27

26Jesus answered them and said, Verily, verily, I say to you, Ye seek me not because ye have seen signs, but because ye have eaten of the loaves and been filled.

27Work not [for] the food which perishes, but [for] the food which abides unto life eternal, which the Son of man shall give to you; for him has the Father sealed, [even] 1God.
