Charles Ellicott Commentary Nehemiah 11:19

"Moreover the porters, Akkub, Talmon, and their brethren, that kept watch at the gates, were a hundred seventy and two." — Nehemiah 11:19 (ASV)

One hundred seventy-two. —In 1 Chronicles 9:0 the number is 212. The difference between the two accounts may partly be explained by the fact that in the Chronicles the list is confined to those who came with Zerubbabel, while here addition is made of those who came with Ezra. But see the commentary on 1 Chronicles 9:0.
