Leviticus 24:3-7

³Without the veil of the testimony in the tabernacle of the covenant. And Aaron shall set them from evening until morning before the Lord, by a perpetual service and rite in your generations.

⁴They shall be set upon the most pure candlestick before the Lord continually.

⁵Thou shalt take also fine hour, and shalt bake twelve leaves thereof, two tenths shall be in every loaf:

⁶And thou shalt set them six and six one against another upon the most clean table before the Lord:

⁷And thou shalt put upon them the dearest frankincense, that the bread may be for a memorial of the oblation of the Lord.
