The gemara in Pesachim ([9b][1]), in discussing the concern that a weasel may drag chometz around the house and leave it in a spot already checked, makes the following exlamation: >וכי חולדה נביאה היא >Is a weasel (chulda) a prophetess? It happens to be there is a prophetess who was named חולדה, as in מלכים ב' פרק כ"ב פסוק י"ד, so... yes, חולדה נביאה היא. Did Chazal intend to make this pun?
