And on the second day thou shalt offer a kid of the goats
without blemish for a sin offering
Jarchi observes, that this was not in the tabernacle, but ordered to be in future time by him that speaks; instead of this, another ram was appointed by the law, ( Exodus 29:15 Exodus 29:19 ) , this shows the ceremonial law to be changeable, and now abolished: this was typical of Christ, without spot and blemish, and yet figured by the goat, being made sin for his people: and they shall cleanse the altar,
as they did cleanse it with the bullock; (See Gill on Ezekiel 43:20).
