Exodus 29:36-38

Amplified Bible, Classic Edition

³⁶ You shall offer every day a bull as a sin offering for atonement. And you shall cleanse the altar by making atonement for it, and anoint it to consecrate it.

³⁷ Seven days you shall make atonement for the altar and sanctify it [set it apart for God]; and the altar shall be most holy; whoever or whatever touches the altar must be holy (set apart for God’s service).

³⁸ Now this is what you shall offer on the altar: two lambs a year old shall be offered day by day continually.
