Dam

('em, ordinary Hebrew word for "mother"): Hebrew law prohibited the destruction of the "dam" and the young of birds at the same time, commanding that if the young be taken from a nest the dam be allowed to escape (De 22:6,7). In the same spirit it enjoined the taking of an animal for slaughter before it had been seven days with its "dam" (Ex 22:30; Le 22:27; compare Ex 23:19).
