Exodus 30:1
Make an altar of acacia wood for burning incense. The altar of incense — the golden altar — is introduced after the ordination ceremony, even though structurally it belongs to the Holy Place alongside the lampstand and the table. The incense altar is smaller than the burnt offering altar: one cubit square and two cubits high. Acacia wood overlaid with gold — the same construction as the other Holy Place furniture. The incense altar stands before the veil, the closest any piece of furniture comes to the Most Holy Place without entering it. The incense that rises from it is the most direct visual representation of prayer ascending to God in the entire tabernacle system.
