George Haydock's Catholic Commentary
Joshua 5:16
Loose. The angel did not only accept of the honour done to him, but also required more, shewing that the field near Jericho was rendered holy, by his presence. (Worthington) --- Hence he ordered Josue to put off his shoes, as Moses had done at the bush, Exodus iii. 5. The Turks leave their shoes at the doors of their mosques, and do not dare to tread on the bare floor. Formerly the pagans would not spit in their temples. (Arrian.) "If, says Porphyrius, in the sacrifices instituted by men, in honour of the gods, people be careful to have their shoes clean, with how much greater attention ought we to preserve our bodies, which are, as it were, the garments of the soul, free from every impurity and corruption!" (Abstin. 2.) (Calmet)
