John Gill Commentary Nehemiah 3:2

"And next unto him builded the men of Jericho. And next to them builded Zaccur the son of Imri." — Nehemiah 3:2 (ASV)

And next to him built the men of Jericho
The posterity of those that formerly inhabited that city; these began where Eliashib and the priests ended, and went on from there:

and next to them;
or rather "to him", the high priest:

built Zaccur the son of Imri;
who probably was the chief of the men of Jericho.
