The very first thing that Bezalel constructed was the Ark of the Covenant, contrary to Moses' order, first to erect the Tabernacle and then to supply its separate furnishings. He succeeded in convincing Moses that it was the proper thing to begin with the Ark, saying: "What is the purpose of this Tabernacle?" Moses: "That God may let His Shekinah rest therein, and so teach the Torah to His people Israel." Bezalel: "And where dost thou keep the Torah?" Moses: "As soon as the Tabernacle shall have been complete, we shall make the Ark for keeping the Torah." Bezalel: "O our teacher Moses, it does not become the dignity of the Torah that in the meanwhile it should lie around like this, let us rather first make the Ark, put the Torah into it, and then continue with the erection of the Tabernacle, for the Tabernacle exists only for the sake of the Torah." Moses saw the justice of this argument, and Bezalel began his work with the construction of the Ark. In this he followed the example of God, who created light before all the rest of the creation. So Bezalel first constructed the Ark that contains the Torah, the light that illuminates this world and the other world; and only then followed the rest. [329] The Ark consisted of three caskets, a gold one, the length of then spans and a fractional part; within this a wooden one, nine spans long, and within this wooden one, one of gold, eight spans long, so that within and without the wooden was overlaid with the golden caskets. The Ark contained the two tables of the Ten Commandments as well as the Ineffable Name, and all His other epithets. The Ark was an image of the celestial Throne, and was therefore the most essential part of the Tabernacle, so that even during the march it was spread over with a cloth wholly of blue, because this color is similar to the color of the celestial Throne. It was through the Ark, also, that all the miracles on the way through the desert had been wrought. Two sparks issued from the Cherubim that shaded the Ark, and these killed all the serpents and scorpions that crossed the path of the Israelites, and furthermore burned all thorns that threatened to injure the wanderers on their march through the desert. The smoke rising from these scorched thorns, moreover, rose straight as a column, and shed a fragrance that perfumed all the world, so that the nations exclaimed: "Who is this that cometh out of the wilderness like pillars of smoke, perfumed with myrrh and frankincense, with all powders of the merchant?"
