Not exactly. While Paul expresses it that way (with full apostolic authority), he teaches the silence of women in church meetings from Scripture. The entire Tanakh (the OT) is also called "the Law". And what does Paul refer to? Let your women keep silence in the churches: for it is not permitted unto them to speak; but they are commanded to be under obedience, as also saith the Law. (1 Cor 14:34). Also, he refers to the deception of Eve (recorded in Genesis) as the basis for disallowing women to preach, teach, or usurp authority in the churches.
Who directed Paul to present these teachings other than God the Holy Spirit, who gave us every epistle by divine inspiration? The words in Scripture are the words of God given to men to write down (2 Tim 3:16,17).
