'Purity' in the Bible

Then she will remain thirty-three days in blood purity. She must not touch anything holy and she must not enter the sanctuary until the days of her purification are fulfilled.

If she bears a female child, she will be impure fourteen days as during her menstrual flow, and she will remain sixty-six days in blood purity.

Such purity characterizes the people who seek his favor, Jacob's descendants, who pray to him. (Selah)

They trample on the dirt-covered heads of the poor; they push the destitute away. A man and his father go to the same girl; in this way they show disrespect for my moral purity.
