Thematic Bible: What to labor for

Jesus answered them, and said - Verily, verily, I say unto you: Ye seek me, not because ye saw signs, but because ye did eat of the loaves and were filled. Be working, not for the food that perisheth, but for the food that endureth unto life age-abiding, - which, the Son of Man, unto you, will give; for upon, the same, hath the Father, even God, set his seal.
