John 6:61 New English Translation

⁶¹When Jesus was aware^[a] that his disciples were complaining^[b] about this, he said to them, “Does this cause you to be offended?^[c]

John 6:61 tn Grk “When Jesus knew within himself.”
John 6:61 tn Or “were grumbling.”
John 6:61 tn Or “Does this cause you to no longer believe?” (Grk “cause you to stumble?”)sn Does this cause you to be offended? It became apparent to some of Jesus’ followers at this point that there would be a cost involved in following him. They had taken offense at some of Jesus’ teaching (perhaps the graphic imagery of “eating his flesh” and “drinking his blood”), and Jesus now warned them that if they thought this was a problem, there was an even worse cause for stumbling in store: his upcoming crucifixion (John 6:61b-62). Jesus asked, in effect, “Has what I just taught caused you to stumble? What will you do, then, if you see the Son of Man ascending where he was before?” This ascent is to be accomplished through the cross; for John, Jesus’ departure from this world and his return to the Father form one continual movement from cross to resurrection to ascension.
