Leviticus 24:2-5

²Command the children of Israel, that they bring to thee pure olive oil beaten for the light, to cause the lamps to burn continually.

³Without the vail of the testimony, in the tabernacle of the congregation, shall Aaron order it from the evening to the morning before the LORD continually: It shall be a statute for ever in your generations.

⁴Ye shall order the lamps upon the pure candlestick before the LORD continually.

⁵And thou shalt take fine flour, and bake twelve cakes of it: two tenth-parts shall be in one cake.
