We have explained in our article Biblical Formatting located on the world wide web at http://www.Rashiyomi.com/biblicalformatting.pdf, that the Biblical Author indicates bold, italics, underline by using repetition. In other words if a modern author wanted to emphasize a word they would either underline, bold or italicize it. However when the Biblical author wishes to emphasize a word He repeats it. The effect - whether thru repetition or using underline - is the same. It is only the means of conveying this emphasis that is different.

Notice the repeated underlined word in the following verse, Ex38-03: And he made the basin of bronze, and its pedestal of bronze, from the mirrors of the affiliating women who affiliated at the door of the Tent of Meeting. As indicated we interpret this repetition as indicating an unspecified emphasis. In modern notation we would translate this sentence with an underline: And he made the basin of bronze, and its pedestal of bronze, from the mirrors of the women who affiliated at the door of the Tent of Meeting. The repetition or underline indicates an unspecified emphasis. Rashi based on the other verse, Ex35-27 translates this emphasis as indicating deliberateness: And he made the basin of bronze, and its pedestal of bronze, from the mirrors of the women who deliberately affiliated at the door of the Tent of Meeting.

Advanced Rashi: We believe the above approach combining three Rashi methods, Other verses, Formatting, Meaning gives a proper natural understanding of Rashi.
