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.

Verse Dt15-08d discussing requirements to the poor states but thou shalt surely open thy hand unto him, and shalt surely lend him sufficient for his losses that he has lost The repeated underlined word phrase lost indicates an unspecified emphasis. Rashi translates this unspecified emphasis as missing losses but not missed out profits That is Rashi translates the verse as follows: supply the poor with his missed losses, but you are not required to supply him with his missed profits. In other words There is a Biblical obligation of charity, to help the poor regain their missed losses But if e.g. a person missed out on an opportunity to make a great profit there is no Biblical obligation to help him recap on the missed profit.
