In his explanation of the parable, Capon hypothesizes that Jesus gives his disciples only what they can handle. He gives them a dog biscuit. (see, Mark 7:27-28).
Capon -Kingdom, Grace, Judgment
Jesus is aware that his teaching ministry has failed. Everyone – from the common laborer to the religious leaders – is looking for a new David to reestablish a Jewish kingdom ruled by God’s Anointed under God’s Law. Jesus has failed to overcome and correct his audience’s grossly mistaken expectations of who he is and what he is proclaiming.
