Leviticus 4:6-7

⁶And when he hath dipped his finger into the blood, he shall sprinkle it seven times before the Lord, against the veil of the saintuary.

⁷And he shall put of the same blood on the corners of the altar of incense most acceptable to the Lord, which altar is in the tabernacle of witnessing; soothly he shall pour all the tother blood into the foundament of the altar of burnt sacrifice in the entering of the tabernacle.
