John Gill Commentary Nehemiah 12:29

"also from Beth-gilgal, and out of the fields of Geba and Azmaveth: for the singers had builded them villages round about Jerusalem." — Nehemiah 12:29 (ASV)

Also from the house of Gilgal
Which likewise was in a champaign country in the plains of Jericho, (Deuteronomy 11:30) (Joshua 5:9Joshua 5:10) ,

and out of the fields of Geba ;
which was a Levitical city in the tribe of Benjamin, (Joshua 21:17)

and Azmaveth ;
the same with Bethazmaveth, (Nehemiah 7:28) where it follows Anathoth and Netophah, as it does in (Ezra 2:24) , and was very probably in the tribe of Benjamin:

for the singers had builded them villages round about Jerusalem ;
that they might be near it, to do their duty when required; by which it appears that the said places were near Jerusalem.
