David sent and took her from her own house into his palace, not by force, but by persuasion, as desiring to speak with her. She came in unto him; into his palace and chamber, as he desired. For she was purified, to wit, from her menstruous pollution, according to the law, Leviticus 18:19; which is here noted as the reason, either why David pursued his lustful desire, or why she so easily yielded to it, because she was not under that pollution which might alienate her from it; or rather, why she so readily conceived, that time being observed by Aristotle and others to be the most likely time for conception.
