Leviticus 24:1-9

The Lord spoke to Moses, saying: “Command the people¹ of Israel to bring you pure oil of beaten olives for the lamp, that a light may be kept burning regularly.² Aaron shall set it up in the tent of meeting, outside the curtain of the covenant, to burn from evening to morning before the Lord regularly; it shall be a statute for ever³ throughout your generations. He shall set up the lamps on the lampstand of pure gold before the Lord regularly.

You shall take choice flour,⁴ and bake twelve loaves of it; two-tenths of an ephah shall be in each loaf. You shall place them in two rows, six in a row, on the table of pure gold. You shall put pure frankincense with each row, to be a token offering for the bread, as an offering by fire to the Lord. Every sabbath day Aaron shall set them in order before the Lord regularly as a commitment of the people of Israel, as a covenant for ever.⁵ They shall be for Aaron and his descendants, who shall eat them in a holy place, for they are most holy portions for him from the offerings by fire to the Lord, a perpetual due.

1 “Command the people” is a phrase that hasn't been used, and seems odd in this context.

2 First mention I recall of keeping a light regularly before God.

3 Another statute to be kept forever.

4 Does not state where flour will come from.

5 Another covenant forever.

Take-home: Additional ordinances are given which insure that oil and bread are regularly provided as signs of Israel's commitment to the temple.
