Shemot 30:7-9

Orthodox Jewish Bible

⁷ And Aharon shall burn thereon spice ketoret every boker; when he cleaneth the nerot (lamps), he shall burn it.

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.
