Two golden stands were placed in the Kodesh near the curtain. During the service of Yom Kippur, the High Priest would sprinkle the blood of the bull inner sin-offering in the Holy of Holies and in front of the curtain. While the High Priest was performing the sprinkling of the blood of the goat inner sin-offering, he would place the vessel containing the blood of the bull on the stand, (and visa versa).
