"And it was on the day that Moses had finished" (Numbers 7:1). Rabbi Yehoshua ben Levi said, "The Holy One, blessed be He, made conditions with Israel before they left Egypt, that He would not take them out, except on condition that they make a tabernacle and that He would have His Divine Presence dwell upon them, as it is written (Exodus 29:46), 'And they shall know that I am the Lord, your God, who took you out of the Land of Egypt, to have Me dwell among you.'" And once the tabernacle was erected, the Divine Presence descended and dwelt among them. At that time all of those conditions were fulfilled. Hence it is written (Numbers 7:1), "the tabernacle," to [indicate] that the Holy One, blessed be He, did what He stipulated.
