Deuteronomy 6:8

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.).

6:8 Tie them: The Lord’s commandments (6:6) were to be as interwoven into the hearts and minds of children as though they were tied to them. Eventually, this figurative phrase in Judaism was practiced literally by wrapping the forearm with cords representing the Torah (see study note on 4:44). • wear them: This figure of speech was represented literally in later Judaism by a small box containing a few brief Torah texts. The box and its contents (Hebrew tefillin; Greek phylactery) were reminders of the need to teach and obey the covenant (cp. 11:18; Matt 23:5).
