Jamieson, Fausset, and Brown
Zidon—famous for its fishery (from a root, Zud, "to fish"); and afterwards for its wide extended commerce; its artistic elegance was proverbial. Founded by Canaan's first-born (Genesis 10:15). Tyre was an offshoot from it, so that it was involved in the same overthrow by the Chaldeans as Tyre. It is mentioned separately, because its idolatry (Ashtaroth, Tammuz, or Adonis) infected Israel more than that of Tyre did (Ezekiel 8:14; Judges 10:6; I Kings 11:33). The notorious Jezebel was a daughter of the Zidonian king.
