Leviticus 4:6 also sprinkles blood seven times before the veil—identical action but for a different offering.

Leviticus 14:7 sprinkles blood seven times on a leper for cleansing, mirroring the sevenfold sprinkling on the altar here.

Ezekiel 43:18-22 details a similar altar purification ritual in the temple vision — mirroring the Day of Atonement cleansing here.

Numbers 19:4 sprinkles blood seven times toward the tent of meeting—same number and method for purification.

Ezekiel 43:20 purifies an altar with blood on its horns—directly parallels the altar cleansing ritual here.

Exodus 29:12 also involves putting blood on altar horns with a finger, but for consecrating priests, not for annual atonement.
