TSK · Exodus 29:33

and you shall eat it in a holy place, because it is your portion, and your sons' portion, of the offerings of Yahweh made by fire: for so I am commanded.

"'No stranger shall eat of the holy thing: a foreigner living with the priests, or a hired servant, shall not eat of the holy thing.

When the tabernacle is to move, the Levites shall take it down; and when the tabernacle is to be set up, the Levites shall set it up. The stranger who comes near shall be put to death.

Those who encamp before the tabernacle eastward, in front of the Tent of Meeting toward the sunrise, shall be Moses, and Aaron and his sons, keeping the requirements of the sanctuary for the duty of the children of Israel. The stranger who comes near shall be put to death.

to be a memorial to the children of Israel, to the end that no stranger, who isn't of the seed of Aaron, comes near to burn incense before Yahweh; that he not be as Korah, and as his company: as Yahweh spoke to him by Moses.

You and your sons with you shall keep your priesthood for everything of the altar, and for that within the veil; and you shall serve: I give you the priesthood as a service of gift: and the stranger who comes near shall be put to death."

Jesus therefore said to them, "Most certainly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you don't have life in yourselves.

For as often as you eat this bread and drink this cup, you proclaim the Lord's death until he comes.
