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