“Speak to Bnei-Yisrael, instructing: If a woman conceives and bears a male child, then she will be unclean for seven days, as in the days of her niddah she will be unclean.
God blessed them and God said to them, “Be fruitful and multiply, fill the land, and conquer it. Rule over the fish of the sea, the flying creatures of the sky, and over every animal that crawls on the land.”
To the woman He said, “I will greatly increase your pain from conception to labor. In pain will you give birth to children. Your desire will be toward your husband, yet he must rule over you.”
Then David sent messengers and took her when she came to him, and he lay with her. (She had purified herself from her uncleanness). Then she returned to her house.
But if she bears a female child, then she will be unclean for two weeks, as in her niddah , and she is to wait in the blood of purification for 66 days.
“If a woman has a discharge, and her discharge from her body is blood, she shall be in her niddah seven days. And whoever touches her will be unclean until the evening.
“Or if he touches some human uncleanness, whatever his filth is by which he is unclean, though it is hidden from him, when he knows of it, then he will be guilty.
