John Wesley on Deuteronomy 11:18

Lay up - Let us all observe these three rules, Let our hearts be filled with the word of God. Lay up these words in your hearts, as in a store - house, to be used upon all occasions. Let our eyes be fixed upon the word of God: Bind them for a sign upon your hand, which is always in view, and as frontlets between your eyes, which you cannot avoid the sight of. Let our tongues be employed about the word of God, especially with our children, who must be taught this, as far more needful than the rules of decency, or the calling they are to live by.
