Not Jeshua the high priest before mentioned, but Jeshua the Levite, (Ezra 2:40) ,

and his brethren, Kadmiel and his sons, the sons of Judah, together ;
the same with Hodaviah, (Ezra 2:40)

to set forward the workmen in the house of God ;
to give them orders to begin and lay the foundation, and hasten and animate them to it:

the sons of Henadad, with their sons and their brethren the Levites :
two of this man's sons are mentioned in (Nehemiah 3:18Nehemiah 3:24) (10:9) .
