Numbers, Chapter 30 - The Vow of Esther

Rabbi David foreman argues that there is another subtle allusion back to this chapter in esther chapter four. In numbers chapter 30, the man has the apparent third option of making himself deaf to his wife's vow - acting as if he is not aware of it. The husband actually accepts his wife's vows by not objecting to it. Esther's preparedness to speak up in relationship to her husband's vow or edict is what changes the situation for the jews. At the suggestion of mordecai, she creatively applies numbers, chapter 30, to herself, and through it, saves her people.
