Ezekiel 45:18

‘And you shall give to the Levitical priests who are from the seed of Zadok, who draw near to Me to minister to Me,’ declares Lord Yahweh, ‘a bull from the herd for a sin offering.

‘When you have finished purifying it, you shall present a bull from the herd without blemish and a ram without blemish from the flock.

“And thus you shall do on the seventh day of the month for everyone who errs or is simpleminded; so you shall make atonement for the house.

‘Thus says Lord Yahweh, “The gate of the inner court facing east shall be shut the six working days; but it shall be opened on the sabbath day and opened on the day of the new moon.
