'Unwell' in the Bible

So Rachel said to her father, “Do not be displeased, my lord, that I cannot rise before you, for the manner of women is on me and I am unwell.” He searched [further] but did not find the household idols.

Say to the children of Israel, If a woman is with child and gives birth to a male child, she will be unclean for seven days, as when she is unwell.

But if she gives birth to a female child, then she will be unclean for two weeks, as when she is unwell; and she will not be completely clean for sixty-six days.

And if a man has sex relations with a woman at the time when she is unwell, he has seen her fountain and she has let the fountain of her blood be uncovered, and the two of them are to be cut off from among their people.
