Zedek or Tzedek, West Semitic for "Justice". Zedek was probably the name of the chief god of the Jebusites, and possibly of other Canaanite people. He is mentioned in the Tanakh and in other middle-eastern writings in conjunction with such Jebusite names as Melchizedek ("My king is Zedek") and Adonizedek (My Lord is Zedek). Some writers have speculated about a connection between Zedek and the planet Jupiter; however, such speculation is not based on any extant archeological evidence.

Zedek, as worshipped by the Jebusites, may have been identical with El or even YHWH.
