🔼The name Zaanan in the Bible
The name Zaanan occurs only once in the Bible, and that in Micah's little list of highly symbolical names (Micah 1:11).
Some of the names of this list belong to well known cities but others are obscure to a point at which one may wonder if Micah made them up for the occasion. Micah is obviously matching the meanings of these names to whatever statement he is making, and that device appears to be much more important than the actual cities themselves.
Zaanan is one of the places that aren't mentioned anywhere else in the Bible, although some scholars have plausibly proposed that it's the same as the town called Zenan (צנן, Joshua 15:37).
🔼Etymology of the name Zaanan
Micah writes, "the inhabitant of Zaanan does not go out," and thus connects the name Zaanan (צאנן) to the verb יצא (yasa'), meaning to go out or go forth:
For a meaning of the name Zaanan, NOBSE Study Bible Name List reads Rich In Flocks, yet the footnote in NOBSE's NAS text says Going Out. Jones' Dictionary of Old Testament Proper Names too reads Rich In Flocks and derives it from an Arabic verb which corresponds to the Hebrew צאן (so'n).
BDB Theological Dictionary does not offer an interpretation of our name and lists it under צאן (so'n), although that might simply be because it's the next word alphabetically.
