Leviticus loves language. It can be hard to see in English, but in the original Hebrew the text is full of puns, links, and callbacks to other biblical texts. Leviticus also moves forward with a series of loops (or "rings") back to the beginning of the book and its various subsections, as if the reader is experiencing the eternal loop of seasons in the circle of life.
As with virtually everything in the book, this all makes a deeper point. The connections and loops in Leviticus point to the connections and cycles in life at large, with the Tabernacle at the center of it all.
Yes, it's truly profound. But it's also a lot more fun to talk about with jokes.
