פירוש על דברים 8:1

כל המצוה — Explain this in its plain sense: EVERY COMMANDMENT. — And a Midrashic explanation is (taking it to mean, “the whole of the commandment … shall ye be heedful to do”): If thou hast once made a beginning with a meritorious deed, carry it out to the end, because it bears the name only of him (it is attributed only to him) who does the last part of it, as it is said, (Joshua 24:32) "And the bones of Joseph which the children of Israel brought up from Egypt they buried in Shechem”. But did not Moses alone busy himself with them to bring them up (cf. Exodus 13:19)? But because he had no opportunity to complete this (to inter them), the children of Israel completed it, it was called by their name (Midrash Tanchuma, Eikev 6).

ALL THE COMMANDMENT. The purport of it is to state: “Although I have admonished you [specifically] with respect to the ordinances,⁵⁶Above, 7:12. all the [other] commandments shall ye observe to do also, for in observing all of them [the ordinances and the commandments] you will live and be fruitful in the fruit of the body, the fruit of the cattle, and the fruit of the ground,” all as mentioned above.⁵⁷Ibid., Verse 13.

כל המצוה אשר אנכי מצוך היום תשמרון לעשות, the objective of people worshipping idols is nothing other than their obsession with transient values which consist mostly of three categories, having children, living to a ripe old age, and success in amassing money or its equivalent. The Torah promises that by observing G’d’s commandments as spelled out in the Torah one may achieve all these three objectives. This is meant by the Torah writing: למען תחיון, when commanding the laws of the Torah G’d did not only mean to guarantee you eternal life in the hereafter, but He had in mind also successful, rewarding life on earth.
