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.

Ezra 8:20 In-Context

18 The gracious hand of our God helped us. So they brought us Sherebiah. He was a man of ability. He came from the family line of Mahli. Mahli was the son of Levi. Levi was a son of Israel. They also brought us Sherebiah's sons and brothers. The total number of men was 18.

19 And they brought Hashabiah and his brothers and nephews. They brought them together with Jeshaiah. He came from the family line of Merari. The total number of men was 20.

20 They also brought 220 of the temple servants. That was a special group David and his officials had established. They were supposed to help the Levites. All of them were listed by name.

21 I announced a fast by the waterway that flows toward Ahava. I told the people not to eat any food. In that way, we made ourselves low in the sight of God. We prayed that he would give us and our children a safe journey. We asked him to keep safe everything we owned.

22 I was ashamed to ask King Artaxerxes for soldiers and horsemen. They could have kept us safe from enemies on the road. But we had told the king that our God would keep us safe. We had said, "The gracious hand of our God helps everyone who looks to him. But he becomes very angry with anyone who deserts him."
