What is the historical background of the mention of 'bread falling from the table' as is seen in Matthew 15:27 (NIV): “Yes it is, Lord,” she said. “Even the dogs eat the crumbs that fall from their master’s table.”
I have seen it claimed in some Bible TV serials that the rich people used to clean their fingers with an inferior kind of bread between one course of meal and another, and then throw those pieces of bread down. Is there any authentic reference to prove that such a practice existed at the time of Jesus?
