Deuteronomy 6:16

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.).

6:16 When Israel journeyed through the Sinai desert after the Exodus, they came to Rephidim, where they found no water (Exod 17:1-7). Moses saw the people’s demand for water as testing the Lord; hence the name Massah (“testing”) for this place. Jesus quoted this verse to rebut Satan (Matt 4:7; Luke 4:12).
