What does Nehemiah 10:39 mean?

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

(The people end by promising not to forget or abandon the temple, making it clear that worship and community life are central.)
