Numbers 23:1

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

"Woe unto them! for they have gone in the way of Cain, and ran greedily after the error of Balaam for reward, and perished in the gainsaying of Core."

"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 on the seventh day seven bullocks, two rams, and fourteen lambs of the first year without blemish:"

"The sacrifice of the wicked is an abomination to the LORD: but the prayer of the upright is his delight."

"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."

"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."
