"The incense had to be vaporized by fire taken off the altar.  The use of other fire brought death, as we have seen.  There is a deep import in this.  The altar is Christ (Heb. 13:10)--the fire, his sufferings.  The prayer of a sinner offered in his own name, or in the name of Mahomet, or in neglect or slight of the Christ-name, is a prayer that will not be as the sweet-smelling incense, but as the pungent and offensive smoke in the nostrils, with which God compares certain people (Isa. 65:5)."  Bro. Roberts, The Law of Moses Pg. 117; The ark and its contents
