7 Aaron must burn fragrant incense on the altar every morning when he tends the lamps. 8 He must burn incense again when he lights the lamps at twilight so incense will burn regularly before the Lord for the generations to come. 9 Do not offer on this altar any other incense or any burnt offering or grain offering, and do not pour a drink offering on it. 10 Once a year Aaron shall make atonement on its horns. This annual atonement must be made with the blood of the atoning sin offering for the generations to come. It is most holy to the Lord.”
Aaron the high priest burns fragrant incense on the altar every morning and evening. Incense symbolise prayer. Our Lord Jesus Christ intercedes for us all the time. All believers are priests of God, therefore we should always pray without ceasing. It reminds us that it is our privilege to come to the presence of God. It is also our duty as a priest to offer prayer (v9-11). God is a holy God, we cannot offer other incense or any burnt offerings. God is a holy God and He takes prayer very seriously because he is listening to our prayer.
