Deuteronomy 12:18; Deuteronomy 12:19

18 Instead, you are to eat them in the presence of the LORD your God at the place the LORD your God will choose—you, your sons and daughters, your male and female servants, and the Levites from your towns—and you are to rejoice before the LORD your God in everything you put your hand to.

19 Be careful not to neglect the Levites as long as you live in your land.
