4. Mose 19:19

Three cities of refuge to be appointed in the midst of the promised land; the land being divided into three parts, a city is to be placed in each, a proper way to which is to be prepared, Deu 19:1-3. In what cases of manslaughter the benefit of those cities may be claimed, Deu 19:4-6. Three cities more to be added should the Lord enlarge their coasts, and the reasons why, Deu 19:7-10. The intentional murderer shall have no benefit from these cities, Deu 19:11-13. The landmark is not to be shifted, Deu 19:14. One witness shall not be deemed sufficient to convict a man, Deu 19:15. How a false witness shall be dealt with - he shall bear the punishment which he designed should have been inflicted on his neighbor, Deu 19:16-20. Another command to establish the lex talionis, Deu 19:21.

THE WATER OF SEPARATION. (Num. 19:1-22) This is the ordinance of the law--an institution of a peculiar nature ordained by law for the purification of sin, and provided at the public expense because it was for the good of the whole community. Speak unto the children of Israel, that they bring thee a red heifer without spot, &c.--This is the only case in which the color of the victim is specified. It has been supposed the ordinance was designed in opposition to the superstitious notions of the Egyptians. That people never offered a vow but they sacrificed a red bull, the greatest care being taken by their priests in examining whether it possessed the requisite characteristics, and it was an annual offering to Typhon, their evil being. By the choice, both of the sex and the color, provision was made for eradicating from the minds of the Israelites a favorite Egyptian superstition regarding two objects of their animal worship.

And the clean person shall sprinkle upon the unclean,.... The clean priest shall sprinkle upon the unclean man, as the Targum of Jonathan; that is, he shall sprinkle the water of purification upon him that is unclean in any of the above ways: on the third day, and on the seventh day; See Gill on Num 19:12, and on the seventh day he shall purify himself; either the unclean person, who shall perfect his purification, as Jarchi interprets it, that is, by doing what follows; or else the clean person, who becomes in some measure unclean, by sprinkling and touching the water of separation, as appears from Num 19:21 as the priest that sprinkled the blood of the heifer, and the man that burnt it and gathered its ashes, Num 19:7. and wash his clothes, and bathe himself in water, and shall be clean at even; in like manner as the man that let go the goat into the wilderness, Lev 16:26.

This chapter is only concerning the preparing and using of the ashes which were to impregnate the water of purification. The people had complained of the strictness of the law, which forbade their near approach to the tabernacle, Num 17:13. In answer to this complaint, they are here directed to purify themselves, so as that they might come as far as they had occasion without fear. Here is, I. The method of preparing these ashes, by the burning of a red heifer, with a great deal of ceremony (Num 19:1-10). II. The way of using them. 1. They were designed to purify persons from the pollution contracted by a dead body (Num 19:11-16). 2. They were to be put into running water (a small quantity of them), with which the person to be cleansed must be purified (Num 19:17-22). And that this ceremonial purification was a type and figure of the cleansing of the consciences of believers from the pollutions of sin appears by the apostle's discourse, Heb 9:13, Heb 9:14, where he compares the efficacy of the blood of Christ with the sanctifying virtue that was in "the ashes of a heifer sprinkling the unclean."
