More than is. . . The מ [of מדי ] means “more than,” as in (Bereishis 29:30), “He loved Rochel more than Leah ( מלאה ).” Rashi adds the phrase, “What was needed for,” because the people brought only what was needed for the work, not the [completed] work itself.

The work of bringing was sufficient . . . Rashi is explaining that the first המלאכה in the verse refers to bringing the donations, and the second, to the actual work of the mishkon.**[Rashi knows this] because if it means the same thing [both times] there is no reason for המלאכה to be mentioned again! Also, [Rashi is explaining that] the suffix of דים refers to the workers.

**As in “( והכבד )**to harden his heart” . . . Rashi is answering the question: Does והותר , [which is in the imperative,] not imply that it is a mitzvah to leave over? But this is not so; there is no such mitzvah. Therefore Rashi explains that it conveys ולְהוֹתִיר , [in the infinitive], and that there are other such words [in the infinitive which are] missing a ל , such as והכבד , [meaning] ולְהַכְבִד , and והכות , [meaning] ולְהַכוֹת .
