New American Standard Bible (NASB)
Numbers 18
28 So you shall also present an offering to the Lord from your tithes, which you receive from the sons of Israel; and from it you shall give the Lord’s offering to Aaron the priest.
29 Out of all your gifts you shall present every offering due to the Lord, from all the best of them, the sacred part from them.’
30 You shall say to them, ’When you have offered from it the best of it, then the rest shall be reckoned to the Levites as the product of the threshing floor, and as the product of the wine vat.
31 You may eat it anywhere, you and your households, for it is your compensation in return for your service in the tent of meeting.
32 You will bear no sin by reason of it when you have offered the best of it. But you shall not profane the sacred gifts of the sons of Israel, or you will die.’"
Numbers 19
1 Then the Lord spoke to Moses and Aaron, saying,
2 "This is the statute of the law which the Lord has commanded, saying, ’Speak to the sons of Israel that they bring you an unblemished red heifer in which is no defect and on which a yoke has never been placed.
3 You shall give it to Eleazar the priest, and it shall be brought outside the camp and be slaughtered in his presence.
4 Next Eleazar the priest shall take some of its blood with his finger and sprinkle some of its blood toward the front of the tent of meeting seven times.
5 Then the heifer shall be burned in his sight; its hide and its flesh and its blood, with its refuse, shall be burned.
6 The priest shall take cedar wood and hyssop and scarlet material and cast it into the midst of the burning heifer.
