Therefore shall ye lay up these my words in your heart and in your soul; and ye shall bind them for a sign upon your hand, and they shall be for frontlets between your eyes.
Let the word of Christ dwell in you richly; in all wisdom teaching and admonishing one another with psalms and hymns and spiritual songs, singing with grace in your hearts unto God.
And it shall be for a sign unto thee upon thy hand, and for a memorial between thine eyes, that the law of Jehovah may be in thy mouth: for with a strong hand hath Jehovah brought thee out of Egypt.
and he said unto them, Set your heart unto all the words which I testify unto you this day, which ye shall command your children to observe to do, even all the words of this law.
