And these words, which I command you this day, shall be in your heart:…
1. At the time this command was given there were few written copies of the whole law, and the people had it read to them only at the Feast of Tabernacles. God, therefore, seemed to have appointed, at least for the present, that some select sentences of the law should literally be written upon their gates and walls, or on slips of parchment to be worn about their wrists or bound upon their foreheads.
2. The spirit of the command, however, and the chief thing intended, undoubtedly was that they should give all diligence, and use all means to keep God's laws always in remembrance; as men frequently bind something upon their hands or put something before their eyes to prevent forgetfulness of a thing that they much desire to remember. But the Jews, forgetting the spirit and design of this precept, used these things as superstitious people do amulets or charms. They used also to put these slips of parchment into a piece of cane or other hollow wood, and fasten that to the door of their houses, and of each particular door in them, and as often as they go in and out they make it a part of their devotion to touch the parchment and kiss it.
