The truth which Christ teaches them in the text, that they were blessed who were pure in heart, was a thing wholly beyond their conceptions. The Jews at this time placed almost the whole of religion in external things, in a conformity to the rites and ceremonies of the law of Moses. They laid great stress on tithing mint, and anise, and cumin, and on their traditions, as in washing hands before meat and the like- but they neglected the weightier matters of the law, and especially such as respected holiness of heart.
