Oil -- typically olive oil -- symbolizes the good that comes from celestial love. Celestial love is love of the Lord, the highest and purest love we can have. The good of celestial love is the desire to be good springing from celestial love: Wanting to do the Lord's will because you love Him. That's not a state many reach, even in heaven, but it's a beautiful goal. This representation makes sense based on the idea that the sun -- the source of all natural light and heat, and thus all natural life -- represents the Lord, the source of all spiritual light, heat and life. Burning oil was the most pure fire available in Biblical times, thus the closest representation of the sun people could create.

5708. 'Five measures more' means that it was much increased. This is clear from the meaning of 'five' as much, dealt with below; and from the meaning of 'measures' as states of truth received from good, dealt with in 3104. As regards 'five', this is a number which can mean little, or else something, or even much. Whatever its specific meaning, this stems from its relationship with the number of which it is a factor, 5291. When it is a factor of ten, much the same as ten, but in a smaller degree, is implied, five being half the number ten. For just as compound numbers have a similar meaning to the simple ones of which they are the product, 5291, 5335, so do divisors have a similar meaning to the compound numbers they divide, as with the relationship of five to ten, also to twenty, as well as to a hundred, a thousand, and so on. 'Ten' means what is full and complete, see 3107, 4638. 'Five measures more' were given to Benjamin than to the rest of his brothers on account of what was meant by this in the spiritual sense. Ten measures could not be given because that amount would have been far too much. The ancients knew from what had been handed down to them from the Most Ancient Church the meanings that certain numbers carried; they therefore used those numbers whenever something cropped up, the meaning of which could be conveyed by those numbers, as is the case with five here. At other times they employed many other numbers, such as three to mean what was complete from start to finish, seven to mean what was holy, or twelve to mean all things in their entirety.
