Leviticus 24:3-7

³Outside the curtain before the covenant decrees in the tent of meeting, Aaron must continually, from evening to morning, keep the lamp lit before Yahweh. This will be a permanent statute throughout your people's generations.

⁴The high priest must always keep the lamps lit before Yahweh, the lamps on the lampstand of pure gold.

⁵You must take fine flour and bake twelve loaves with it. There must be two-tenths of an ephah in each loaf.

⁶Then you must set them in two rows, six in a row, on the table of pure gold before Yahweh.

⁷You must put pure incense along each row of loaves as a representative offering. This incense will be burnt for Yahweh.
