John 4:32-33
“I have meat to eat that you know not of. Therefore, said the disciples one to another, Hath any man brought Him anything to eat?”
Why now do you wonder that the woman when she heard of “water,” still imagined mere water to be meant, when even the disciples are in the same case, and as yet suppose nothing spiritual, but are perplexed? Though they still show their accustomed modesty and reverence toward their Master, conversing one with the other, but not daring to put any question to Him. And this they do in other places, desiring to ask Him, but not asking. What then says Christ?
