'Infirmity' in the Bible

Speak unto the children of Israel, saying, If a woman conceive seed, and bear a male, then she shall be unclean seven days; as in the days of the separation of her infirmity shall she be unclean.

And if a man shall lie with a woman in her infirmity, and uncover her nakedness, her flux doth he lay bare, and she hath uncovered the fountain of her blood; and both of them shall be cut off from among their people.
