Rashi, in his comments towards the beginning of Parshat Pekudei (Shemot 38:22,) tells us about a strange debate that took place between Moshe Rabbeinu and Betzalel, the person in charge of building the Mishkan. Moshe commanded Betzalel to first make the vessels and only afterwards to build the building-structure of the Mishkan, but Betzalel refused to follow that order, insisting that "the common practice of the world is to first make a house, and afterwards to put furnishings into it."
Rabbi Moshe Weinberger explains that this debate was rooted in Moshe and Betzalel's respective opinions on the subject of how to balance bitachon (faith) and hishtadlut (effort.) Of course, there is a wide spectrum of possibilities, but the question becomes which value to prioritize. Moshe believed that that one should primarily live with bitachon, while Betzalel thought one should primarily live with hishtadlut. (In practice, the balance is very personal and individualized.)
