Exodus 30:1-10

“Then make another altar of acacia wood for burning incense. Make it 18 inches square and 36 inches high, with horns at the corners carved from the same piece of wood as the altar itself. Overlay the top, sides, and horns of the altar with pure gold, and run a gold molding around the entire altar. Make two gold rings, and attach them on opposite sides of the altar below the gold molding to hold the carrying poles. Make the poles of acacia wood and overlay them with gold. Place the incense altar just outside the inner curtain that shields the Ark of the Covenant, in front of the Ark’s cover—the place of atonement—that covers the tablets inscribed with the terms of the covenant. I will meet with you there. “Every morning when Aaron maintains the lamps, he must burn fragrant incense on the altar. And each evening when he lights the lamps, he must again burn incense in the LORD’s presence. This must be done from generation to generation. Do not offer any unholy incense on this altar, or any burnt offerings, grain offerings, or liquid offerings. “Once a year Aaron must purify the altar by smearing its horns with blood from the offering made to purify the people from their sin. This will be a regular, annual event from generation to generation, for this is the LORD’s most holy altar.”
