12. Salute it. As they could not distinguish the devout worshippers of God from despisers, he enjoins them to address in a friendly manner any family which they may have occasion to meet. The act of saluting is a kind of opening to a conversation. They had already been warned to look out for persons to entertain them, whose religious zeal was generally known and believed.

Commenting on Matthew 10:5-15
