Hanani seems to have been an actual brother of Nehemiah Neh 7:2.

I asked them concerning the Jews - Josephus gives a probable account of this business: "Nehemiah, being somewhere out of Susa, seeing some strangers, and hearing them converse in the Hebrew tongue, he went near; and finding they were Jews from Jerusalem, he asked them how matters went with their brethren in that city, and what was their state?" And the answer they gave him is, in substance, that recorded in the text; though with several aggravations in Josephus. - Joseph. Ant. lib. xi., c. 5.

That Hanani, one of my brethren,.... Either in natural relation, Nehemiah 7:2, or being a Jew of the same nation and religion; so Jarchi interprets it, one of my companions or acquaintance:

he and certain men of Judah; who came from thence to Shushan on some account or another:

and I asked them concerning the Jews that had escaped, which were left of the captivity; who were returned from it to their own land; he inquired of their health and prosperity, in what circumstances they were, whether prosperous or adverse, whether they flourished, or were in distress:

and concerning Jerusalem; whether it was rebuilt, the houses and walls of it, and in what condition it was.

There came to Nehemiah Hanani, one of his brethren, and certain men from Judah. מאחי אחד, one of my brethren, might mean merely a relation of Nehemiah, אחים being often used of more distant relations; but since Nehemiah calls Hanani אחי in Nehemiah 7:10, it is evident that his own brother is meant. "And I asked them concerning the Jews, and concerning Jerusalem." היּהוּדים is further defined by וגו הפּליטה, who had escaped, who were left from the captivity; those who had returned to Judah are intended, as contrasted with those who still remained in heathen, lands. In the answer, Nehemiah 1:3, they are more precisely designated as being "there in the province (of Judah)." With respect to המּדינה, see remarks on Ezra 2:1. They are said to be "in great affliction (רעה) and in reproach." Their affliction is more nearly defined by the accessory clause which follows: and the wall equals because the wall of Jerusalem is broken down, and its gates burned with fire. מפרצת, Pual (the intensive form), broken down, does not necessarily mean that the whole wall was destroyed, but only portions, as appears from the subsequent description of the building of the wall, Nehemiah 3.

That Hanani, one of my {b} brethren, came, he and certain men of Judah; and I asked them concerning the Jews that had escaped, which were left of the captivity, and concerning Jerusalem.

(b) A Jew as I was.

2, 3. Hanani, one of my brethren, came, he and certain men of Judah-Hanani is called his brother (Ne 7:2). But as that term was used loosely by Jews as well as other Orientals, it is probable that no more is meant than that he was of the same family. According to Josephus, Nehemiah, while walking around the palace walls, overheard some persons conversing in the Hebrew language. Having ascertained that they had lately returned from Judea, he was informed by them, in answer to his eager enquiries, of the unfinished and desolate condition of Jerusalem, as well as the defenseless state of the returned exiles. The commissions previously given to Zerubbabel and Ezra extending only to the repair of the temple and private dwellings, the walls and gates of the city had been allowed to remain a mass of shattered ruins, as they had been laid by the Chaldean siege.

1:15-44 The best reformers can but do their endeavour; when the Redeemer himself shall come to Zion, he shall effectually turn away ungodliness from Jacob. And when sin is repented of and forsaken, God will forgive it; but the blood of Christ, our Sin-offering, is the only atonement which takes away our guilt. No seeming repentance or amendment will benefit those who reject Him, for self-dependence proves them still unhumbled. All the names written in the book of life, are those of penitent sinners, not of self-righteous persons, who think they have no need of repentance.
