Of Phadaia were born Zorobabel and Semei. Zorobabel beget Mosollam, Hananias, and Salomith their sister:

From Pedaiah, there rose up Zerubbabel and Shimei. Zerubbabel conceived Meshullam, Hananiah, and their sister Shelomith,

Zerubbabel, elsewhere always called "the son of Salathiel," was only Salathiel's heir and legal son, being naturally his nephew, the son of his brother, Pedaiah.

The sons of Pedaiah - Houbigant thinks these words should be omitted. Pedaiah is wanting in the Arabic and Syriac. If this be omitted, Zerubbabel will appear to be the son of Salathiel, according to Matthew 1:12, and not the son of Pedaiah, as here stated.

And the sons of Pedaiah [were], (f) Zerubbabel, and Shimei: and the sons of Zerubbabel; Meshullam, and Hananiah, and Shelomith their sister:
(f) Matthew says that Zerubbabel was the son of Shealtiel, meaning that he was his nephew according to the Hebrew speech: for he was Pedaiah's son.

And the sons of Pedaiah were, Zerubbabel and Shimei,.... Here arises a difficulty, since elsewhere Zerubbabel is said to be the son of Shealtiel, Haggai 1:1 some think this is not the same Zerubbabel here as there; so Grotius (u); but I see no reason for that; but this difficulty may be removed by observing, that if Pedaiah was a son of Salathiel, as Kimchi thinks, then Zerubbabel, being his grandson, may be called his son, as grandsons are sometimes called sons in Scripture; or rather, Salathiel, having no children, adopted Zerubbabel, his brother's son, and made him successor in the government; so that he was the son of Pedaiah by birth, and of Salathiel by adoption; or else Salathiel dying without children, his brother Pedaiah, according to the law, married his widow, and by her had Zerubbabel, who was the proper son of Pedaiah, and the legal son of Salathiel:
and the sons of Zerubbabel; Meshullam: who is called Abiud, Matthew 1:13 another son of his, with their father, is mentioned in this verse, and five more in the next. From hence to the end of the chapter, the genealogy is carried on from the captivity of Babylon, out of which Zerubbabel came, to the coming of Christ; and if Ezra was the writer of this book, as is generally thought, who was contemporary with Zerubbabel, this account must be written by another hand: and it may be observed, that it is carried on in the same number of generations as in Matthew; and here it stands thus:
Zerubbabel, Hananiah, Jesaiah, Rephaiah, Arnan, Obadiah, Shecaniah, Shemaiah, Neariah, Elioenai, Anani; in Matthew thus, "Zerubbabel, Abiud, Eliakim, Azor, Sadoc, Achim, Eliud, Eleazar, Matthan, Jacob, Joseph"; the difference in names may be accounted for by their having two names; and it is remarkable that the Targum makes Anani to be the King Messiah, who was to be revealed; which, though it makes one generation less to his time, yet plainly shows that the Jews expected the Messiah to come at the end of this genealogy, and about the time Jesus the true Messiah did. Anani is reckoned by other Jews a name of the Messiah, who is said to come in the clouds of heaven, which "Anani" signifies; see Gill on Daniel 7:13.
(u) In Luc. 3.

Their sister - Sister to the two last named sons of Zerubbabel, namely, by both parents; and therefore named before the other five, 1-Chronicles 3:20, who were her brethren by the father, but not by the mother.
