After the Lord's revelation at Horeb/Sinai, he commanded Moses to teach Israel the ordinances of the Lord, in order for Israel to do them in the Promised Land. This recollection by Moses occurs at a time where once again he is teaching Israel, this time the post-Sinai generation, the ordinances of the Lord prior to their entry into the land of promise.
14 En ce temps-là, l'Eternel me commanda de vous enseigner des lois et des ordonnances, afin que vous les mettiez en pratique dans le pays dont vous allez prendre possession.
