So, you see that since generic applies to all women, then it wouldn’t be necessary for Paul to switch to a generic, since he was already speaking generically to all women. He would have continued on saying let all women learn, and learn in quietness and submission without domineering men. But the fact that the switch is so out of place and obvious says to me that we cannot ignore it, that it has a purpose. To further that thought Paul CONTINUES with the singular, even citing a singular woman, Eve (with her husband Adam), as an example. Paul stays with this singular deliberately until the very end, when he switches deliberately into a plural.
