John 6:23-27

(howbeit there came boats from Tiberias nigh unto the place where they ate the bread after the Lord had given thanks): when the multitude therefore saw that Jesus was not there, neither his disciples, they themselves got into the boats, and came to Capernaum, seeking Jesus. And when they found him on the other side of the sea, they said unto him, Rabbi, when camest thou hither? Jesus answered them and said, Verily, verily, I say unto you, Ye seek me, not because ye saw signs, but because ye ate of the loaves, and were filled. Work not for the food which perisheth, but for the food which abideth unto eternal life, which the Son of man shall give unto you: for him the Father, even God, hath sealed.
