פירוש על שמות 27:20

ואתה תצוה ... זך CLEAR — without lees; and this was effected not by straining the oil but as we learn in Treatise Menachoth 86a “He lets it (the olive) ripen on the top of the olive-tree etc.”

Scripture states here, and thou shalt command [and does not say, “command the children of Israel”], because He always said with reference to the Tabernacle and thou shalt make,¹Above, 25:11, etc. which means by your command [i.e., “you Moses command them to do it”]. Therefore He said here “and you yourself command them that they bring to you the oil for the light.” [It says that they bring and not “that they make”] because they had no way of making the oil in the wilderness; [therefore they were told] to bring it if they had it in reserve. Actually it were the princes that brought it.²Further, 35:27-28.

ואתה תצוה, If, prior to this admonition, the Torah introduced its instructions with the words ועשית, “you will do, etc.,” the meaning had been that Moses was not to do this personally, but that he was to delegate the tasks in question. The formulation ואתה, however, means: “and you personally.” He, personally, was to issue instructions to the Israelites concerning providing the oil for the Menorah. He, personally, was to assemble Aaron and his sons and to address all the חכמי לב, “wise-hearted people.” (28,1 and 28,3)
