Leviticus 20:20-21 - Exposition

They shall die childless;… they shall be childless. "It cannot be supposed that a perpetual miracle was to be maintained through all the ages of Israel's history; but the meaning evidently is that the children of such marriages should be reckoned, not to their actual father, but to the former husband of the woman. In the strong feeling of the Israelites in regard to posterity, this penalty seems to have been sufficient" (Gardiner).
