Numbers 28:2

צו את בני ישראל COMMAND THE CHILDREN OF ISRAEL — What is said above? Moses said, “Let the Lord set [a man over the congregation]” (Numbers 27:16). The Holy One, blessed be He, said to him, “Instead of giving Me a command regarding My children, command My children regarding Me!” A parable! It may be compared to the case of a princess who was departing this world and gave her husband charge concerning her children, etc., as it is related in Sifrei Bamidbar 142:1. קרבני MY OFFERING — this refers to the blood. לחמי MY FOOD — this refers to the fat-portions, and so it states, (Leviticus 3:16) “And the priest shall burn them (the fat-portions) on the altar, it is the food of the fire-offerings” (Sifrei Bamidbar 142:2). לאשי [MY FOOD] FOR MY FIRE OFFERING — i.e., the fat-portions that are assigned for the fire offerings of My altar (Sifrei Bamidbar 142:2). תשמרו YE (the children of Israel) SHALL WATCH [TO OFFER TO ME] — This implies that priests, Levites and ordinary Israelites shall stand by watching when the sacrifices are offered (Sifrei Bamidbar 142:2). From this command they (the Rabbis) derived the law of, and instituted the Maamadot (representatives of the people who were present when the sacrificial service was performed) (Taanit 27a). במועדו [YE SHALL OFFER TO ME] IN ITS APPOINTED SEASON — Every day is the “appointed season” for the continual offerings.

צַ֚ו אֶת־בְּנֵ֣י יִשְׂרָאֵ֔ל וְאָמַרְתָּ֖ אֲלֵהֶ֑ם אֶת־קׇרְבָּנִ֨י לַחְמִ֜י לְאִשַּׁ֗י רֵ֚יחַ נִֽיחֹחִ֔י תִּשְׁמְר֕וּ לְהַקְרִ֥יב לִ֖י בְּמוֹעֲדֽוֹ׃

Command the children of Yisra᾽el, and say to them, My offering, the provision of my sacrifices made by fire, for a sweet savour to me, shall you observe to offer to me in their due season.
