Exodus 30:7-10 ▼

7 “Every morning when Aaron maintains the lamps, he must burn fragrant incense on the altar.

8 And each evening when he lights the lamps, he must again burn incense in the LORD’s presence. This must be done from generation to generation.

9 Do not offer any unholy incense on this altar, or any burnt offerings, grain offerings, or liquid offerings.

10 “Once a year Aaron must purify the altar by smearing its horns with blood from the offering made to purify the people from their sin. This will be a regular, annual event from generation to generation, for this is the LORD’s most holy altar.”
