Albert Barnes Commentary Ezra 3:2

"Then stood up Jeshua the son of Jozadak, and his brethren the priests, and Zerubbabel the son of Shealtiel, and his brethren, and builded the altar of the God of Israel, to offer burnt-offerings thereon, as it is written in the law of Moses the man of God." — Ezra 3:2 (ASV)

Jeshua, the high priest, was the son of Jozadak, who was carried into captivity by Nebuchadnezzar (1 Chronicles 6:15).

Zerubbabel was really the son of Pedaiah, Shealtiel’s (or Salathiel’s) younger brother. But Shealtiel having no sons, and the royal line being continued in the person of his nephew, Zerubbabel, the latter was accounted Shealtiel’s son.
