Ezra 8:20 Meaning and Commentary

Ezra 8:20

Also of the Nethinims, whom David and the princes had
appointed for the service of the Levites
To wait upon them, and minister to them, as they did to the priests; some think those were the same with the Gibeonites, whom Joshua gave to the service of the sanctuary, and David confirmed; but others are of opinion these were different from them, and an addition to them:

two hundred and twenty Nethinims: all of them were expressed by
name;
in the history that Iddo sent of them to Ezra; and so the names of the Levites, though not here expressed, only the names of those they came with.

18 And by the good hand of our God upon us, they brought us a man of discretion, of the sons of Mahli the son of Levi, son of Israel, namely Sherebi'ah with his sons and kinsmen, eighteen;

19 also Hashabi'ah and with him Jeshai'ah of the sons of Merar'i, with his kinsmen and their sons, twenty;

20 besides two hundred and twenty of the temple servants, whom David and his officials had set apart to attend the Levites. These were all mentioned by name.

21 Then I proclaimed a fast there, at the river Aha'va, that we might humble ourselves before our God, to seek from him a straight way for ourselves, our children, and all our goods.

22 For I was ashamed to ask the king for a band of soldiers and horsemen to protect us against the enemy on our way; since we had told the king, "The hand of our God is for good upon all that seek him, and the power of his wrath is against all that forsake him."
