Ark

And Betsalel made the Ark..This is what the verse says: Beginning of your words will give light (Psalms 119). When the Holy One Blessed be He desired to make the world, he enclothed Himself in light (which was the first thing said to be created in Genesis), as it says: He wears light as a garment (Psalms 103). From the Holy One, the righthouse learned to start with light. When He commanded Moshe to build the Tabernacle, he (in turn) said to Betsalel: begin with the Ark. (Therefore,) Betsalel made the Ark (Yalkut Shemos 37).

The Midrash teaches us that all our projects, even building G-d's abode, must begin with Torah. In a wider sense, it declares that worship must start from and contain within it Hashem's teachings for it is within those that He is enclothed and it is in them that He may be located.
