John 6:62-64

World English Bible

⁶² Then what if you would see the Son of Man ascending to where he was before? ⁶³ It is the spirit who gives life. The flesh profits nothing. The words that I speak to you are spirit, and are life. ⁶⁴ But there are some of you who don’t believe.” For Jesus knew from the beginning who they were who didn’t believe, and who it was who would betray him.
