Leviticus 24:6

Outside of the veil of the Testimony, in the Tent of Meeting, Aaron shall keep it in order from evening to morning before the LORD continually. It shall be a statute forever throughout your generations.

He shall keep in order the lamps on the pure gold lamp stand before the LORD continually.

“You shall take fine flour, and bake twelve cakes of it: two tenths of an ephah shall be in one cake.

You shall put pure frankincense on each row, that it may be to the bread for a memorial, even an offering made by fire to the LORD.

Every Sabbath day he shall set it in order before the LORD continually. It is an everlasting covenant on the behalf of the children of Israel.

It shall be for Aaron and his sons. They shall eat it in a holy place; for it is most holy to him of the offerings of the LORD made by fire by a perpetual statute.”
