Exodus 13:9  (King James Version)
And it shall be for a sign unto thee upon thine hand, and for a memorial between thine eyes, that the LORD'S law may be in thy mouth: for with a strong hand hath the LORD brought thee out of Egypt.
 


a sign
This expression, says Michaelis, alludes to the custom of the Orientals, of burning in their right hand all kinds of marks with the ashes of henna, which gives an indelible colour; and this is done even to this day. They were likewise accustomed to write all kinds of sayings, and frequently superstitious words, on slips or pieces of linen, which they wore as ornaments on their foreheads.
