Exodus 30:7-10 ▼

7 On it Aaron shall burn fragrant incense. Morning after morning, when he prepares the lamps,

8 and again in the evening twilight, when he lights the lamps, he shall burn incense. Throughout your generations this shall be the regular incense offering before the LORD.

9 On this altar you shall not offer up any profane incense, or any burnt offering or grain offering; nor shall you pour out a libation upon it.

10 Once a year Aaron shall purge its horns. Throughout your generations he is to purge it once a year with the blood of the atoning purification offering. This altar is most sacred to the LORD.
