John 6:62-64

Complete Jewish Bible

⁶² Suppose you were to see the Son of Man going back up to where he was before? ⁶³ It is the Spirit who gives life, the flesh is no help. The words I have spoken to you are Spirit and life, ⁶⁴ yet some among you do not trust.” (For Yeshua knew from the outset which ones would not trust him, also which one would betray him.)
