John Gill Commentary Nehemiah 7:2

"that I gave my brother Hanani, and Hananiah the governor of the castle, charge over Jerusalem; for he was a faithful man, and feared God above many." — Nehemiah 7:2 (ASV)

That I gave my brother Hanani
Who first brought him the melancholy account of the state of Jerusalem, (Nehemiah 1:2Nehemiah 1:3) ,

and Hananiah the ruler of the palace ;
the king's palace, in which the viceroy of the king of Persia dwelt, and now Nehemiah; to these two men he gave

charge over Jerusalem ;
committed it to their care during his absence, who may be supposed now to return to Persia, as he had promised, (Nehemiah 2:6) ,

for he was a faithful man ;
this is said of Hananiah, and given as a reason why such a trust was committed to him; Hanani's character was well known, and his journey from Jerusalem to Shushan was a full proof of his hearty concern for the interest of it:

and feared God above many ;
Hananiah was exemplary in his fear of God, few were equal to him, and none exceeded him; or of many days, as Jarchi; of a long time he had feared the Lord, and served him many years.
