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 indicated bullets by using repeating keywords.

That is, if a modern author wanted to get a point across using bullets - a list of similar but contrastive items - then the Biblical Author would use repeating keywords. Today's verse illustrates this principle.

Bullets whether indicated through modern notation or through the Biblical method of repeating keywords always indicate contrastive emphasis - that is, each bullet is presumed to be a distinct item contrasted to the other items on the list. Very often the bullets are also used to indicate that the entire list of exhaustive of some spectrum.

Verse(s) Gn47-24b discussing the food and seed which Pharoh gave the Egyptian people states And it shall come to pass at harvest time, that you shall give the fifth part to Pharaoh, and four parts shall be
• for you, [Obvious meaning: For you, your spouses and the adults in your family]
• for seed of the field, [Rashi: For next years planting] and
• for your food,[Obvious meaning: Seed for you - whether for planting or for eating] and
• for them of your households, [Rashi: Including servants] and
• for food for your little ones.[Rashi: Including all children]
The repeated underlined phrase for creates a bullet effect. The bullet effect in turn creates an emphasis on the distinctness of all enumerated items. Rashi interprets the distinctness as indicated in the bracketed items in the above list. Notice how Rashi applies the bullet principles: Each bullet refers to a distinct item; the bullets together should cover all cases.
