27Labour not Labour not: or, Work not for the meat which perisheth, but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed.
English Standard Version
27 Do not labor for the food that perishes, but for the food that endures to eternal life, which the Son of Man will give to you. For on him God the Father has set his seal."
27 "Don't waste your energy striving for perishable food like that. Work for the food that sticks with you, food that nourishes your lasting life, food the Son of Man provides. He and what he does are guaranteed by God the Father to last."
New King James Version
27 Do not labor for the food which perishes, but for the food which endures to everlasting life, which the Son of Man will give you, because God the Father has set His seal on Him."
New Living Translation
27 But don't be so concerned about perishable things like food. Spend your energy seeking the eternal life that the Son of Man can give you. For God the Father has given me the seal of his approval."
Instead of answering the inquiry how he came there, Jesus blamed their asking. The utmost earnestness should be employed in seeking salvation, in the use of appointed means; yet it is to be sought only as the gift of the Son of man. Him the Father has sealed, proved to be God. He declared the Son of man to be the Son of God with power.
