Ze’dad (mountain side), one of the landmarks on the north border of the land of Israel, as promised by Moses, Num. 34:8, and as restored by Ezekiel. Ezek. 47:15. A place named Sudud exists to the east of the northern extremity of the chain of Anti-Libanus, about fifty miles east-northeast of Baal-bec. This may be identical with Zedad.
