John 6:26-27

²⁶Jesus answered them and said, 'Verily, verily, I say to you, Ye seek me, not because ye saw signs, but because ye did eat of the loaves, and were satisfied;

²⁷work not for the food that is perishing, but for the food that is remaining to life age-during, which the Son of Man will give to you, for him did the Father seal — even God.'
