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 Lv17-13 discussing the slaughter of animals/birds states A person who hunts [any] hunt of [any] edible animal or venizon, he shall pour out the blood and cover it with dust. The repeated underlined word phrase hunt hunt indicates an unspecified emphasis. Rashi translates this unspecified emphasis as indicating Hunts a hunt emphasizes any hunt - that is, a hunt of any animal or bird, even domesticated animals/birds such as chickens. That is Rashi translates the verse as follows: A person who hunts [any] hunt of [any] edible animal or venizon, he shall pour out the blood and cover it with dust. It follows that the requirement to cover the blood of a slaughtered animal applies both to animals that are typically hunted as well as to domesticated animals.
