What qualities are we looking for in artisans who would build the Mishkan? We would think craftsmanship -but did the Israelite Mishkan artisans have any training, or were they inspired by God with a spirit of voluntarism and goodwill?

We are looking for spiritual qualities to build a physical mishakan for for spiritual purpose. Why was Betzalel the best? He was  the most singled out because he had the best spiritual qualities-always  tasked with the jobs with the highest spiritual import, beause he had the wisdom, insight, and understanding for this spiritual endeavor.
