In Timothy it says that "the woman may not teach them." But if you read closely it is definitely singular, not plural. Also Timothy was a letter from Paul to Timothy, who was teaching at the time, so its possible that there was a single person who Timothy was having trouble with. While some people claim that the Bible says women cannot teach men, the argument against that are the points I mentioned above.
1Timothy 2:11-12 "Let a women learn in quietness in all submissiveness; but I do not permit a woman to teach nor to dictate to a man, but to be in quietness. For Adam was formed first, then Eve; and Adam was not deceived, but the women was befooled into violation of the command." (The Bible in Living English)
