15 An objection was raised: All those who are obliged to take the ritual bath must take the bath at night.<span class="x" onmousemove="('comment',' Meg. 20a, based on Num. XIX, 19, for the law that all may bathe during the day: And on the seventh day he shall purify him and bathe himself in water and be clean at even. - That a menstruant must not bathe before the night of the seventh day is inferred from Lev. XV,19: And if a woman have an issue, she shall be in her impurity seven days. A woman after confinement is compared to a menstruant in Lev.
