5. Mose 6:9

Moses, in this chapter, goes on with his charge to Israel, to be sure to keep up their religion in Canaan. It is much the same with ch. 4. I. His preface is a persuasive to obedience (Deu 4:1-3). II. He lays down the great principles of obedience. The first truth to be believed, That God is one (Deu 4:4). The first duty to be done, To love him with all our heart (Deu 4:5). III. He prescribes the means for keeping up religion (Deu 4:6-9). IV. He cautions them against those things which would be the ruin of religion - abuse of plenty (Deu 4:10-12), inclination to idolatry (Deu 4:14, Deu 4:15), and gives them some general precepts (Deu 4:13, Deu 4:16-18). V. He directs them what instructions to give their children (Deu 4:20, etc.).

6:9 Write them on the doorposts: In later Judaism, people placed portions of Deuteronomy in a small metal case (a mezuzah) attached to the doorframes of houses or other buildings. It was customary to touch the mezuzah when passing through the doorway to show respect for and dependence upon the Scripture.
