What does Nehemiah 10:39 mean?

The people of Israel, including the Levites, will bring their contributions of grain, new wine, and oil to the storerooms, where the temple vessels, the serving priests, the gatekeepers, and the singers are. We won't neglect God's house. Nehemiah 10:39 - Modern Text Bible

(They end by promising not to forget or abandon the temple, making it clear that worship and God's presence are at the center of their community life.)
