Exodus 30:1

Verse 1. An altar to burn incense. This burning of incense was an emblem of prayer, ascending to God from an inflamed heart. See Psalms 140:2. Revelation 5:8 and 8:4. Challoner.—Nothing but incense was daily offered by the high priest upon this altar. On the day of expiation he touched the four corners with blood. It stood over-against the bread of proposition.
