As Jesus is troubled in spirit…He knows what looms. The disciples don’t know exactly, but I bet they do not like the way He is beginning to talk. Surely, they could see in His body language that He was visibly troubled. I suspect He wasn’t one to hide His feelings. So, He has told them that He is about to go away, and they can’t go with Him. In fact, He told them that things were about to get so bad Peter would deny Him three times
before the night is over.
