John Gill Commentary Nehemiah 12:38

"And the other company of them that gave thanks went to meet them, and I after them, with the half of the people, upon the wall, above the tower of the furnaces, even unto the broad wall," — Nehemiah 12:38 (ASV)

And the other company of them that gave thanks went
over against them
On the left hand, on the northern part of the wall:

and I after them ;
Nehemiah, he brought up the rear of his company, as Ezra led the van of his:

and the half of the people upon the wall ;
the chief of them, for all could not walk upon it:

from beyond the tower of the furnaces ;
where they baked their bread, or their bricks, see (Nehemiah 3:11) ,

even unto the broad wall ;
where the wall was broader than common, for some reason or another, see (Nehemiah 3:8) .
