You shall set the golden altar of incense in front of the ark of the Testimony [outside the veil], and put the [hanging] veil at the doorway of the tabernacle.
and they shall take all the utensils of the service with which they minister in the sanctuary, and put them in a blue cloth, and cover them with a covering of porpoise skin, and put them on the carrying bars.
and they shall put on it a covering of porpoise skin (fine leather), and shall spread over that a cloth of pure blue, and shall insert the carrying poles of the ark.
Another angel came and stood at the altar. He had a golden censer, and much incense was given to him, so that he might add it to the prayers of all the saints (God’s people) on the golden altar in front of the throne. [Ps 141:2]
