John 6:26, 60, 66

Jesus answered, “I assure you and most solemnly say to you, you have been searching for Me, not because you saw the signs (attesting miracles), but because you ate the loaves and were filled.

When many of His disciples heard this, they said, “This is a difficult and harsh and offensive statement. Who can [be expected to] listen to it?”

As a result of this many of His disciples abandoned Him, and no longer walked with Him.
