Deuteronomy 12:17-19

CLV(i) 17 You cannot eat within your gates the tithe of your grain, of your grape juice and of your clarified oil, neither the firstlings of your herd and your flock nor any of your vow offerings which you shall vow, neither your voluntary offerings nor the heave offerings of your hand. 18 But rather you shall eat it before Yahweh your Elohim in the place that Yahweh your Elohim shall choose, you, your son and your daughter, your servant and your maidservant and the Levite who is within your gates. Then you will rejoice before Yahweh your Elohim in every undertaking of your hand. 19 Guard yourself lest you should forsake the Levite any of your days on your ground.
