I noticed an apparent conflict when the Torah uses units of a large number. It seems to occur with mentioning someone's age.
Examples:
Breishit 23:1 Sarah lived 100 years and 20 years and 7 years
vs.
Breishit 47:28 Jacobs' life was 7 years and 40 and 100 years
In the first case, the units are in descending value (100, then 20, then 7). IN the 2nd, they are in ascending value (7, then 40, then 100.)
I assume this is some general grammatical rule, and I surmise that if each unit is separated with the word "years", then it is descending, otherwise itWhy is ascending. If this,there a change in fact, is the rule, why is it this wayordering of the units?
