The parable - The "obscure" and difficult remarks which he had made in Mark 7:15. The word "parable," here, means "obscure" and "difficult saying." They could not understand it. They had probably imbibed many of the popular notions of the Pharisees, and they could not understand why a man was not defiled by external things. It was, moreover, a doctrine of the law that men were ceremonially polluted by contact with dead bodies, etc., and they could not understand how it could be otherwise.
And when he was entered into the house,.... Very probably at Capernaum, and it may be the house of Simon and Andrew, where he used to be when there:
from the people; being separated from them, having dismissed and left them, when he and his disciples were by themselves alone:
his disciples asked him concerning the parable; that saying of his to the people, which was somewhat dark and intricate to them; that nothing without a man going into him defiled him, but what comes out of him: this was asked by Peter, in the name of the rest; See Gill on Matthew 15:15.
