Matthew 10:11

And there abide.

Why?

(1) That they might not appear changeable:

(2) That they might not hurt the feelings of their first host;

(3) That they might not incur the charge of being gluttonous hankerers after the boards of the rich. (Lapide.)

Free hospitality in the East

When travelling in the East no one need scruple to go into the best house of any Arab village to which he comes, and he will be received with profuse and gratuitous hospitality. From the moment we entered any house, it was regarded as our earn. There is not an Arab you meet who will not empty for you the last drop in his water-skin, or share with you his last piece of black bread. The Rabbis said that paradise was the reward of willing hospitality. (Ernest Renan.)
