Thanks for starting it off. What has my focus is the Babylonian currency.
The three words were common ones in the Chaldaic language, but they also were words used to describe units of Babylonian money. The base unit of their ancient monetary system was the gerah. Twenty of these gerahs formed one shekel [or, tekel]. One thousand gerahs made a Minah [or, Mena]. While there was no coin known as a Peres or Upharsin [the plural of Peres], the word meaning division was used as we use the word half in much the same manner as we refer to a half dollar. It referred to a half Minah(* see below), being equal to 500 gerahs. Treating these words as monetary units, then, we find:
Mena 1000 gerahs
Mena 1000 gerahs
Tekel 20 gerahs
Upharsin 500 gerahs
Total 2520 gerahs
times of the Gentiles happens to be 2,520 ?
