Deuteronomy 6:9 - Clarke's commentary and critical notes on the Bible

And thou shalt write them upon the posts of thy house, and on thy gates. Write them upon the posts of thy house, and on thy gates - The Jews, forgetting the spirit and design of this precept, used these things as superstitious people do amulets and charms, and supposed, if they had these passages of Scripture written upon slips of pure parchment, wrapped round their foreheads, tied to their arm, or nailed to their door-posts, that they should then be delivered from every evil! And how much better are many Christians, who keep a Bible in their house merely that it may keep the devil out; and will have it in their rooms, or under their pillows, to ward off spirits and ghosts in the night? How ingenious is the heart of man to find out every wrong way, and to miss the right!
