It is not a secret that we are called Jews after the tribe of Judah. From that and other factors, (David, Messiah, etc.) we understand that Judah was the “most important” or “highest valued” tribe.
The question is: What is the “lowest” tribe? The answer is: … Dan, and for many reasons (among them, Samson who works alone, Jacob blesses Dan as a serpent, the story of idolatry of Moses’ grandson, etc.).
Maybe that is the reason two people are chosen to build the tabernacle, Bezalel, the son of Uri, the son of Hur, of the tribe of Judah, and Oholiab, the son of Ahisamach, of the tribe of Dan.
Only when everyone is represented, when everyone is included, the “highest” and the “lowest”, can we build a place where G-d can reside.
