Commentary for Exodus 36:7

והמלאכה היתה דים (lit., and the work was their sufficiency — was enough for them — for all the work) — this means the work of contributing was the sufficiency of (was enough for) the workers at the Tabernacle, for all the work connected with the Tabernacle to make it and even to leave some over.

והמלאכה היתה דים, the work performed by volunteers for all spheres of the artisanship and craftsmanship required was adequate for the needs of the project

דים…והותר, sufficient and too much. How could there be "too much" and "sufficient" at the same time? There seems to be something contradictory here. Why did the Torah have to mention that "the work was sufficient" at all? The Torah only needed to inform us that the requirements for the Holy Tabernacle were oversubscribed! Besides, the entire verse seems superfluous as we have already been told in verse five that the people brought more than was required and had to be restrained. Obviously, such a statement had to be based on the quantities having already been either counted, weighed or measured!
