Ezra 2:60 Meaning and Commentary

Ezra 2:60

The children of Delaiah, the children of Tobiah, and the
children of Nekoda, six hundred fifty and two.
] These, though their immediate parents were known, yet by their being mentioned here, it seems as if they could not carry their genealogy further, and make it clearly appear what was the house of their fathers, or what their family.

Ezra 2:60 In-Context

58 The total number of descendants of the temple workmen and of Solomon's servants who returned from exile was 392.
59 There were 652 belonging to the clans of Delaiah, Tobiah, and Nekoda who returned from the towns of Tel Melah, Tel Harsha, Cherub, Addan, and Immer;
60 but they could not prove that they were descendants of Israelites.
61 The following priestly clans could find no record to prove their ancestry: Habaiah, Hakkoz, and Barzillai. (The ancestor of the priestly clan of Barzillai had married a woman from the clan of Barzillai of Gilead and had taken the name of his father-in-law's clan.)
62 Since they were unable to prove who their ancestors were, they were not accepted as priests.
