Those are actually great questions so to address those questions:
1) Women teaching - translation issues:
First, and for me probably the most important, if it was the law for women not to teach then Miriam, Deborah, Huldah, Priscilla, and Phoebe wouldn't have been teaching and Paul would have corrected it.
So, we have to find out why to the scriptures mentioned.
1) The word for women and wives in the Greek are exactly the same so we have to look at the context. Does it mean wife or woman and does it mean man or husband because the English translation doesn't always translate accordingly.
2) Additionally, women in those days did not receive an education. The growth curve to have them catch up was immense. If but the culture of having someone to stay and take care of the children. No daycares, no both parents having a job. That wasn't the culture of that time
3) Last, in other parts of scripture, we have to remember that men and women didn't sit together in the synagogue/church. Culture. That also created a problem. (This is happening in some places even today)
Deborah, TaNaKh, was a judge. She both taught and judged - that didn't change in the advent of Jesus... it was enlarged so that in Christ, there was neither male nor female.
Priscilla, along with her husband, is someone Paul names as a “co-worker” in Christ, and in Acts 18, Priscilla teaches Apollos, a “learned man, with a thorough knowledge of scripture.” Thus, a woman was teaching a man.
The biggest issue that they wanted to address was usurping authority. The enthusiasm of their newfound faith had the pendulum swinging too far so... Timothy:
11 Let the woman learn in silence with all subjection. 12 But I suffer not a woman to teach, nor to usurp authority over the man, but to be in silence.13 For Adam was first formed, then Eve.
the context is "marriage" as in Adam and Eve. "learn in silence" has to do with a synagogue/church where women were on one side or in the back as also dictated in Corinthians (same issue)
1 Corinthians 14:35
And if they will learn any thing, let them ask their husbands at home: for it is a shame for women to speak in the church.
Not that they couldn't learn but in the Corinthian church there was such disorder that having women speak from one side of the aisle to the other so "learn at home" was the direction.
Later in years, women learned and became pastors.
16 I commend unto you Phebe our sister, which is a servant of the church which is at Cenchrea:2 That ye receive her in the Lord, as becometh saints, and that ye assist her in whatsoever business she hath need of you: for she hath been a succourer of many, and of myself also.3 Greet Priscilla and Aquila my helpers in Christ Jesus:4 Who have for my life laid down their own necks: unto whom not only I give thanks, but also all the churches of the Gentiles.5 Likewise greet the church that is in their house. Salute my well-beloved Epaenetus, who is the firstfruits of Achaia unto Christ.
This is a great supportive scripture... Not only is Phebe mentioned but Priscilla was mentioned before her husband (she taught Apollos) and naming her first gives the understanding that she was the leader at her home church.
