I think this means feather.
However I don’t think this is a big deal.
You know the old joke about the physicist who tried to get out of a ticket for running a red light, who said that because of spectrum shift, the light looked green as he approached. But the prosecutor knew physics too, and asked the physicist to calculate his speed, whereupon he was convicted of speeding.
God knows how to work all these details together into a beautiful whole, but we need to respect His ways of doing it. We aren’t deity — thank goodness, because if we were, we would muff it.
I know that's right.
