What does Ezra 3:2 mean?

Jeshua son of Jozadak and his fellow priests, along with Zerubbabel son of Shealtiel and his relatives, started building the altar of Israel’s God so they could offer burnt offerings, just as it’s written in the Law of Moses, God’s man. Ezra 3:2 - Modern Text Bible

(The leaders took the initiative to rebuild the altar first, making worship their top priority, following the traditions handed down from Moses.)
