Zerubbabel led one group of Hebrews back to Judah after the Babylonian exile. At the time of Haggai’s ministry, he served as the Persian-appointed governor of Judah (see Ezra 2:1–2; 3:2; Nehemiah 7:7).
Jeshua was the high priest at that time. He supervised the rebuilding of the altar and the dedication of the second temple (Ezra 3:2; 5:2; 6:15).
