What does Deuteronomy 12:18 mean?

You and your family, your workers, and the Levites must eat those things together in the presence of the Lord your God, in the place he chooses. Celebrate all the good things the Lord your God has given you. Deuteronomy 12:18 - Modern Text Bible

(Worship is communal and joyful, shared with everyone, especially those who depend on the community, like the Levites.)
