7 And on this altar sweet spices are to be burned by Aaron every morning when he sees to the lights. 8 And every evening, when he puts the lights up in their places, the spices are to be burned, a sweet-smelling smoke going up before the Lord from generation to generation for ever. 9 No strange perfume, no burned offering or meal offering, and no drink offering is to be offered on it.
Matthew Henry's Commentary on Exodus 30:7-9
Commentary on Exodus 30:1-10
(Read Exodus 30:1-10)
The altar of incense represented the Son of God in his human nature, and the incense burned thereon typified his pleading for his people. The continual intercession of Christ was represented by the daily burning of incense thereon, morning and evening. Once every year the blood of the atonement was to be applied to it, denoting that the intercession of Christ has all its virtue from his sufferings on earth, and that we need no other sacrifice or intercessor but Christ alone.
