Leviticus 24:1

1And the Lord spake unto Moses, saying,

2Command the children of Israel, that they bring unto thee pure oil olive 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 unto the morning before the Lord continually: it shall be a statute for ever in your generations.

4He shall order the lamps upon the pure candlestick before the Lord continually.

5And thou shalt take fine flour, and bake twelve cakes thereof: two tenth deals shall be in one cake.
