zil'-pa (zilpah, meaning uncertain; Zelpha): The ancestress of Gad and Asher (Ge 30:10,12; 35:26; 46:18), a slave girl of Leah's, given her by Laban (Ge 29:24; 30:9). In Eze 48 the Zilpah tribes have the 5th division toward the South of Palestine and the 6th to the North, a slightly more favorable position than that of the Bilhah tribes.
