1 And the LORD spake unto Moses and unto Aaron, saying,
2This is the ordinance of the law which the LORD hath commanded, saying, Speak unto the children of Israel, that they bring thee a red heifer without spot, wherein is no blemish, and upon which never came yoke:
3 And ye shall give her unto Eleazar the priest, that he may bring her forth without the camp, and one shall slay her before his face:
God said to Moses and Aaron,
Say to the Israelites,
This is the ordinance that I command:
Bring an unblemished, spotless red heifer which has never been under the yoke. 
Eleazar will kill it.
4 And Eleazar the priest shall take of her blood with his finger, and sprinkle of her blood directly before the tabernacle of the congregation seven times:
He will take its blood with his finger and sprinkle it seven times in front of the tabernacle. 
5 And one shall burn the heifer in his sight; her skin, and her flesh, and her blood, with her dung, shall he burn:
Burn the heifer, with her skin, flesh, blood, and dung.
6 And the priest shall take cedar wood, and hyssop, and scarlet, and cast it into the midst of the burning of the heifer.
The priest will take cedar wood, hyssop, and scarlet and cast it onto the burning heifer.
7 Then the priest shall wash his clothes, and he shall bathe his flesh in water, and afterward he shall come into the camp, and the priest shall be unclean until the even.
8 And he that burneth her shall wash his clothes in water, and bathe his flesh in water, and shall be unclean until the even.
Then he will wash his clothes, bathe his flesh, and be unclean until the evening.
9And a man that is clean shall gather up the ashes of the heifer, and lay them up without the camp in a clean place, and it shall be kept for the congregation of the children of Israel for a water of separation: it is a purification for sin.
10 And he that gathereth the ashes of the heifer shall wash his clothes, and be unclean until the even: and it shall be unto the children of Israel, and unto the stranger that sojourneth among them, for a statute forever.
A man who is clean will gather the ashes and put them in a clean place.
These ashes will be used to make a water of separation, a purification for sin.

11He that toucheth the dead body of any man shall be unclean seven days.
Whoever touches a dead body is unclean for 7 days. 
12 He shall purify himself with it on the third day, and on the seventh day he shall be clean: but if he purify not himself the third day, then the seventh day he shall not be clean.
If he purifies himself on the third day, he will be clean on the seventh day.
But if he doesn't, he won't be clean.
13Whosoever toucheth the dead body of any man that is dead, and purifieth not himself, defileth the tabernacle of the LORD; and that soul shall be cut off from Israel: because the water of separation was not sprinkled upon him, he shall be unclean; his uncleanness is yet upon him.

On the seventh day, the unclean person must wash his clothes, bathe in water, and will be clean in the evening. 
20But the man that shall be unclean, and shall not purify himself,that soul shall be cut off from among the congregation, because he hath defiled the sanctuary of the LORD: the water of separation hath not been sprinkled upon him; he is unclean.
But if the man that is unclean doesn't purify himself according to the above procedure, he is unclean.
21 And it shall be a perpetual statute unto them, that he that sprinkleth the water of separation shall wash his clothes; and he that toucheth the water of separation shall be unclean until even.
This is a perpetual statute.
22And whatsoever the unclean person toucheth shall be unclean; and the soul that toucheth it shall be unclean until even.
