"But if she is cleansed from her discharge... on the eighth day, she shall take for herself two turtledoves..."Leviticus 15:28-29.

A woman who is a zavah [one who experiences menses three consecutive days outside the normal menstrual period] must, after the disorder has been cured, bring an offering—two pigeons or two turtledoves.

Until she brings this offering, her purification process is not complete and she may not partake of sacrificial flesh.
