🔼The name Zenan in the Bible
The name Zenan occurs only once in the Bible. It belongs to one of the cities in the lowland of Judah at the time of the division of Canaan. We don't hear of this place anymore, which isn't all that unusual, but it may or may not be the same as the Judaic town of Zaanan mentioned by Micah (Micah 1:11).
🔼Etymology of the name Zenan
The name Zenan (צנן) could be a contracted form of Zaanan (צאנן) in which case it probably comes from the noun צאן (so'n), meaning flock. But it may very well also come from any of the roots צנן (snn):
For a meaning of the name Zenan, both NOBSE Study Bible Name List and Jones' Dictionary of Old Testament Proper Names go with the noun צאן (so'n) and translate Zenan as Place Of Flocks (while both read Rich In Flocks for Zaanan).
BDB Theological Dictionary neither offers an interpretation of our name nor lists it under any particular root.
