פּירוש אויף דברים 5:29

Now observe to practice The purpose of this seemingly redundant verse is to add the injunction do not turn aside to the right or the left .

YE SHALL OBSERVE TO DO, THEREFORE, AS THE ETERNAL YOUR G-D COMMANDED YOU. This warning alludes to the Ten Commandments which G-d Himself communicated to them directly, and afterwards he admonished them with respect to the rest of the commandments which they said they [preferred to] hear from Moses and [they promised] to perform them. Therefore, he said, And this is the commandment, the statutes, and the ordinances which the Eternal your G-d commanded to teach you,²⁰⁰Further, 6:1. since G-d agreed to your request and He commanded me to teach you the entire balance of the Torah, that ye may live,²⁰¹Verse 30. that He may fulfill the number of your days,²⁰²See Exodus 23:26. and that it may be well with you²⁰¹Verse 30. with all the good that He promised you in the section of If ye walk in My statutes²⁰³Leviticus 26:3. and other sections besides; and that ye may prolong your days in the Land²⁰¹Verse 30. that you will inherit for your children forever.

ושמרתם לעשות, seeing that things have developed in this fashion it is no more than a minimal request that you observe and carry out G’d’s commandments,
