²⁷ Do not work for food that perishes, but for food that endures [and leads] to eternal life, which the Son of Man will give you; for God the Father has authorized Him and put His seal on Him.”

⁴⁸ I am the Bread of Life [the Living Bread which gives and sustains life].

⁶³ It is the Spirit who gives life; the flesh conveys no benefit [it is of no account]. The words I have spoken to you are spirit and life [providing eternal life].
