The Lord therefore taught his disciples to offer peace on their entering into a house, that by means of their salutation their choice might be directed to a worthy house and host. As though He had said, Offer peace to all, they will shew themselves either worthy by accepting, or unworthy by not accepting it; for though you have chosen a hose that is worthy by the character he bears among his neighbours, yet ought you to salute him, that the preacher may seem rather to enter by invitation, than to intrude himself. This salutation of peace in few words may indeed by referred to the trial of the worthiness of the house or master.
