פרשת תצוה תשי"ט - קרבן התמיד

And this is what you shall offer. The purpose of the altar could not have been for the sacrificing of sin offerings because God did not want people to sin in the first place. Rather, its primary purpose was for the sacrificing of the continual offerings, which were expressions of gratitude for God’s kindnesses to the B’nei Yisrael. Thus the morning offering recalled the Giving of the Torah, which took place in the morning. The afternoon sacrifice recalled the redemption from Egypt, which took place in the evening. The tenth of an epha of flour recalled the manna, of which each person received a tenth of an epha every day. The oil recalled the distinction they received at the time of the exodus and the wine recalled their joy.

Now this is that which thou shalt offer upon the altar: two lambs of the first year day by day continually.

And with the one lamb a tenth part of an ephah of fine flour mingled with the fourth part of a hin of beaten oil; and the fourth part of a hin of wine for a drink-offering.

And they shall know that I am the LORD their God, that brought them forth out of the land of Egypt, that I may dwell among them. I am the LORD their God.

לשכני בתכם means under the condition that I may dwell in the midst of them.

They will know … to dwell among them. They will know that God brought them out of Egypt solely in order to in the Sanctuary that they would build for Him.
