Exodus 3:5

Put off thy shoes. — Rather, thy sandals. It is doubtful whether shoes were known at this early date. They would certainly not have been worn in Midian. Egyptians before the time of Moses, and Orientals generally, in ancient (as in modern) times, removed their sandals (or their shoes) from their feet on entering any place to which respect was due, as a temple, a palace, and even the private house of a great man. It is worthy of notice that God Himself orders this mark of respect to be shown to the place which His Presence has hallowed. On the reverence due to holy places, see the Note on Genesis 28:16.
