According to Torah can a woman become a messenger?
The answer to this depends on the mitzvah involved. For mitzvos that a woman is herself obligated in, a woman can become an envoy, or a shaliach. Therefore, a woman can be an envoy for lighting chanukah candles, because she is also obligated in the mitzvah. However, for mitzvos that a woman is not obligated in, such as teaching one’s son Torah, she cannot be an envoy.
