Again you MUST ( but certainly don't )understand the conditions in Jerusalem and Judah when Isaiah was prophesying the judgements of God to come. They were under Assiryan dominance ( Babylon had begun ). This judgement was on the wicked who had turned away from and forsaken God and had provoked the anger of the Holy One of Israel. Ba'al worship was in full swing. These were not women of God. The women AND men had fallen into paganism and idolatry. God was speaking judgement to the WICKED. Read 3:10 and see that it was well with the righteous and 3:11 to see woe unto the wicked. READ your Bible! This was not concerning the women who still obeyed the law ( there were many ).
Funny, you quote only two scriptures repetitively while the bible has numerous other scriptures ( OT and NT )citing women who were used of God ( prophetess publicly speaking, judges, interpretors or verifiers of the law to their husbands, etc. )in the company of men that you choose to ignore. Strange that you can find no verse in which Jesus, the fulfillment of the law, says nothing about this being out of His will. Odd that you ignore biblical history and customs of such.
