Shemot 30:8-10

Orthodox Jewish Bible

⁸ And when Aharon lighteth the nerot (lamps) in the afternoon, he shall burn ketoret upon it, ketoret tamid before Hashem throughout your dorot.

⁹ Ye shall offer no ketoret zarah thereon, nor olah, nor minchah; neither shall ye pour nesekh thereon.

¹⁰ And Aharon shall make kapporah upon the karenot of it once in a year with the dahm of the chattat hakippurim; once in the year shall he make kapporah upon it throughout your dorot; it is kodesh kodashim unto Hashem [see Lev 16 on this].
