Exodus 30:1-8

“You shall make an altar upon which to burn incense; you shall make it of acacia wood. It shall be a cubit long and a cubit wide. It shall be square and it shall be two cubits high. Its horns of one piece with it. You shall overlay it with pure gold, its top and its sides all around, and its horns; and you shall make a gold molding all around it. You shall make two gold rings under its molding, make them on the two side walls—on opposite sides—they shall be holders for the poles with which to carry it. You shall make the poles of acacia wood overlaid with gold. You shall put the altar of incense [in the Holy Place] in front and outside of the veil that screens the ark of the Testimony, before the mercy seat that is over the Testimony, where I will meet with you. Aaron shall burn sweet and fragrant incense on it; he shall burn it every morning when he trims and tends the lamps. [Ps 141:2; Rev 5:8; 8:3, 4] When Aaron sets up the lamps at twilight, he shall burn incense, a perpetual incense before the LORD throughout your generations.
