'Child' in the Bible

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.

Or your father's wife's daughter, the child of your father, for she is your sister.

But if a priest's daughter is a widow, or parted from her husband, and has no child, and has come back to her father's house as when she was a girl, she may take of her father's bread; but no outside person may do so.
