Zur in the Bible Encyclopedia - ISBE
zur (tsur "rock"):
(1) A prince or chief (Nu 25:15; 31:8) of Midian, father of
the woman slain with Zimri by Phinehas. Josh 13:21 describes
him as one of the princes of Sihon, but the reference there is
regarded as a gloss.
(2) An inhabitant of Gibeon (1 Ch 8:30; 9:36), to be connected
probably, according to Curtis, with "Zeror" of 1 Sam 9:1.
