Ezekiel 43:22

And on the second day thou shalt offer a kid of the goats without blemish for a sin offering; and they shall cleanse the altar, as they did cleanse it with the bullock.

Cross-reference

Ezekiel 43:20 describes the bull purification ritual that the goat in verse 22 is told to follow — 'as they purified it with the bull'.

Ezekiel 43:25 extends the purification — a male goat daily for seven days — showing the multi-day process that begins with this second-day goat.

Ezekiel 43:26 concludes the seven-day atonement process that verse 22 begins on day two — part of the same ritual sequence.

Ezekiel 45:18 commands a bull sin offering for purifying the sanctuary, similar to the goat sin offering for altar purification in verse 22 — both cleanse the holy place.
