Deuteronomy 6:6-8

Verse 6

Shall be in thine heart - For where else can love be? If it be not in the heart, it exists not. And if these words be not in the heart - if they are not esteemed, prized, and received as a high and most glorious privilege, what hope is there that this love shall ever reign there?
Verse 7

Thou shalt teach them diligently - שננתם shinnantam, from שנן shanan, to repeat, iterate, or do a thing again and again; hence to whet or sharpen any instrument, which is done by reiterated friction or grinding. We see here the spirit of this Divine injunction. God's testimonies must be taught to our children, and the utmost diligence must be used to make them understand them. This is a most difficult task; and it requires much patience, much prudence, much judgment, and much piety in the parents, to enable them to do this good, this most important work, in the best and most effectual manner. See at the end of this chapter, Deu 6:25 (note).

And shalt talk of them when thou sittest in thine house - Thou shalt have religion at home, as well as in the temple and tabernacle.

And when thou walkest by the way - Thou shalt be religious abroad as well as at home, and not be ashamed to own God wheresoever thou art.

When thou liest down, and when thou risest up - Thou shalt begin and end the day with God, and thus religion will be the great business of thy life. O how good are these sayings, but how little regarded!
Verse 8

Thou shalt bind them for a sign upon thins hand - Is not this an allusion to an ancient and general custom observed in almost every part of the world? When a person wishes to remember a thing of importance, and is afraid to trust to the common operations of memory, he ties a knot on some part of his clothes, or a cord on his hand or finger, or places something out of its usual order, and in view, that his memory may be whetted to recollection, and his eye affect his heart. God, who knows how slow of heart we are to understand, graciously orders us to make use of every help, and through the means of things sensible, to rise to things spiritual.

And they shall be as frontlets - טטפת totaphoth seems to have the same meaning as phylacteries has in the New Testament; and for the meaning and description of these appendages to a Jew's dress and to his religion, see the notes on Exo 13:9, and Mat 23:5 (note), where a phylactery is particularly described.
