New International Version - UK

³⁴ And if any of the meat of the ordination ram or any bread is left over till morning, burn it up. It must not be eaten, because it is sacred.

³⁵ ‘Do for Aaron and his sons everything I have commanded you, taking seven days to ordain them. ³⁶ Sacrifice a bull each day as a sin offering to make atonement. Purify the altar by making atonement for it, and anoint it to consecrate it.
