Adam Clarke on 1 Timothy 2:12

Nor to usurp authority - A woman should attempt nothing, either in public or private, that belongs to man as his peculiar function. This was prohibited by the Roman laws: In multis juris nostri articulis deterior est conditio foeminarum quam masculorun,; l. 9, Pap. Lib. 31, Quaest. Foeminoe ab omnibus officiis civilibus vel publicis remotae sunt; et ideo nec judicis esse possunt, nec magistratum gerere, nec postulare, nec pro alio invenire, nec procuratores existere; l. 2, de Reg. Juris. Ulp. Lib. i. Ad Sab. - Vid. Poth. Pand. Justin., vol. i. p. 13. "In our laws the condition of women is, in many respects, worse than that of men. Women are precluded from all public offices; therefore they cannot be judges, nor execute the function of magistrates; they cannot sue, plead, nor act in any case, as proxies." They were under many other disabilities, which may be seen in different places of the Pandects.

But to be in silence - It was lawful for men in public assemblies to ask questions, or even interrupt the speaker when there was any matter in his speech which they did not understand; but this liberty was not granted to women. See the note on 1Cor 14:34, 1Cor 14:35 (note).
