John Gill Commentary Nehemiah 3:8

"Next unto him repaired Uzziel the son of Harhaiah, goldsmiths. And next unto him repaired Hananiah one of the perfumers, and they fortified Jerusalem even unto the broad wall." — Nehemiah 3:8 (ASV)

Next unto him repaired Uzziel the son of Harhaiah, of the
goldsmiths
Or Tzorephim, which, according to Jarchi, was the name of a family so called from their trade and business:

next unto him also repaired Hananiah the son of one of the
apothecaries ;
or confectioners, which also might be the name of a family so called for the same reason:

and they fortified Jerusalem unto the broad wall ;
which reached from the gate of Ephraim to the corner gate, which was broken down by Joash, king of Israel, but was rebuilt so strong by Uzziah, king of Judah, that it stood firm to this time; wherefore these men repaired up to it, but left that as they found it; see (2 Chronicles 25:23) (26:9) , and were not careful to repair it, it not wanting any repair.
