(31:2) See, I have selected Betzalel son of Uri son of Chur, of the tribe of Judah, by name.
See, I have selected Betzalel … by name R. Shmuel b. Nachmani said: The name Betzalel—which means “in the shadow of the Almighty”—was given to him to signify that he would become a person of great wisdom. How was his wisdom evident? When God said to Moses: Go and tell Betzalel to build Me a tabernacle, an ark, and vessels—in that order; first the building and then its contents (31:7)—Moses reversed the order and said to Betzalel: Make an ark, vessels, and a tabernacle—first the ark and then the tabernacle—as they are listed in Parashat Terumah (25:10–25:40). Betzalel said to Moses: As a rule, a person first builds a house, and then he brings the contents into it, but you say: Make an ark, vessels, and then a tabernacle. Where shall I put the vessels that you are telling me to make? Could it be that God told you: Make a tabernacle, an ark, and vessels? Replied Moses: You must have been “in the shadow of the Almighty, ” and that's how you knew (Berachot 55a)!
NOTE: Moses reversed the order, because the ark, which was the purpose for which the tabernacle was built, was uppermost in his mind.
