Grinding

~Luke 17.35 Two women will be grinding flour together at the mill; one will be taken, the other left.

It's a stretch, but I'm inclined to make an argument for whole grain here--women grinding the wheat (or maybe some other grain) for the day's flour for the daily bread. These moms aren't picking up a loaf of Wonder Bread at the local market. Surely it's like Great Harvest, ground fresh daily with none of the nutrient-dense parts thrown out to make a lighter, whiter product.
