Exodus 30:7-9

7Aaron is to burn sweet incense on it morning by morning; when he attends to the lamps he is to burn incense.

8When Aaron sets up the lamps around sundown he is to burn incense on it; it is to be a regular incense offering before the Lord throughout your generations.

9You must not offer strange incense on it, nor burnt offering, nor meal offering, and you must not pour out a drink offering on it.
