So you didn't actually get a response that you wanted, you didn't get
the A record for your requested support.ourfirst.org

You are missing the DNS zone in your DNS configuration for
support.ourfirst.org. The NS record in ourfirst.org indicates that the
server ns.ourfirst.org is the server responsible for the zone, but the
zone either isn't created or has been created and BIND hasn't been
reloaded to re-read the new configuration.

The reason the server wont return the NS record when queried directly
is because that is a glue record only, the zone didn't exist so there
was no response to return.
