Ezekiel

Therefore take unto you now seven bullocks and seven rams, and go to my servant Job, and offer up for yourselves a burnt offering; and my servant Job shall pray for you: for him will I accept: lest I deal with you after your folly, in that ye have not spoken of me the thing which is right, like my servant Job.

But ye shall offer an offering made by fire unto the Lord seven days: in the seventh day is an holy convocation: ye shall do no servile work therein.

And it came to pass, when God helped the Levites that bare the ark of the covenant of the Lord, that they offered seven bullocks and seven rams.

And they brought seven bullocks, and seven rams, and seven lambs, and seven he goats, for a sin offering for the kingdom, and for the sanctuary, and for Judah. And he commanded the priests the sons of Aaron to offer them on the altar of the Lord.

And Balaam said unto Balak, Build me here seven altars, and prepare me here seven oxen and seven rams.
