According to the author of Nehemiah, this verse tells us about important leaders from a long time ago, like Joiakim, Jeshua, Nehemiah, and Ezra, who helped guide and teach the people. It shows us how they worked together to keep everything in order and help everyone follow God's rules.
Nehemiah 12:26: These [were] in the days of Joiakim the son of Jeshua, the son of Jozadak, and in the days of Nehemiah the governor, and of Ezra the priest, the scribe.
Nehemiah 12:26 lists the leaders of the priests and Levites at a particular point, but Ezra provides different names for priests and Levites returning with Zerubbabel, suggesting discrepancies in records or lists of leading figures.
Ezra 2:36-40: The priests: the children of Jedaiah, of the house of Jeshua, nine hundred seventy and three.
