Aaron was to burn sweet incense upon this altar every morning and every evening, which was intended not only to take away the ill smell of the flesh that was burned daily on the brazen altar, but for the honour of God, and to show the acceptableness of his people's services to him. As by the offerings on the brazen altar satisfaction was made for what had been done displeasing to God, so by the offering on this, what they did well was, as it were, recommended to the divine acceptance.
