John Gill's Bible Commentary Ver. 2. The Lord our God made a covenant with us in Horeb .] Which is Sinai, as Aben Ezra observes; it being the same mountain, only it had two tops, which bore these different names; for certain it is that the decalogue after repeated was given at Sinai, and had the nature and form of a covenant; (see Exodus 24:7,8).
Matthew Henry Commentary
Verses 1-5 - Moses demands attention. When we hear the word of God we must learn it and what we have learned we must put in practice, for that is the en of hearing and learning; not to fill our heads with notions, or ou mouths with talk, but to direct our affections and conduct.
