(14) A wife and her mother.--See Leviticus 18:17.

They shall be burnt with fire.--This, as we have seen, is the second of the four modes of capital punishment. (See Leviticus 20:2.) In the following ten cases those guilty of the sins specified suffered this punishment: (1) the unchaste high priest's daughter (Leviticus 21:9); (2) he who had commerce with his daughter; (3)or with his daughter's daughter; (4) or with his son's daughter; (5) or with his wife's daughter; (6) or with her daughter's daughter; (7) or with her son's daughter; (8) or with his mother-in-law; (9) or with the mother of his mother-in-law; and (10), or with the mother of his father-in-law. It will thus be seen that with the exception of the high priest's daughter this death was only inflicted for incest. As the Bible nowhere states the precise mode in which this kind of death is to be carried out, the authorities during the second Temple maintained that it must be executed in such a manner as to leave the body externally un changed by the flames, because, when God himself inflicted this punishment, the dead bodies of Nadab and Abihu were in a perfect state of preservation. (See Leviticus 10:2.) To effect this the criminal was put into dung up to his knees, a soft cloth containing a hard one was then tied around his throat, while the two witnesses who had secured his sentence drew tighter by the two cords till the criminal opened his mouth, when molten lead was poured down his throat, thus burning him to death. Hence the ancient Chaldee Version renders it here, "they shall be burnt with fire, with melted lead in their mouth."

20:10-27 These verses repeat what had been said before, but it was needful there should be line upon line. What praises we owe to God that he has taught the evil of sin, and the sure way of deliverance from it! May we have grace to adorn the doctrine of God our Saviour in all things; may we have no fellowship with unfruitful works of darkness, but reprove them.And if a man take a wife, and her mother,.... Marry both the one and the other, or commit uncleanness with them, they consenting to it:

it is wickedness; abominable wickedness, shocking and detestable; there are other things, which also are wicked and not to be done, but this is extremely wicked, wickedness to a high degree:

they shall be burnt with fire, both he and they; the man, the mother and her daughter both being married together to him, or both consenting to his lying with them; otherwise, if one of them was first his wife, it was not reasonable that she should be put to death; and therefore some interpret "they", one of them, as Jarchi observes, one or other of them; and so Aben Ezra explains it, this or that; if the mother was his wife, the daughter was to be burnt; and so on the contrary, if the daughter was his wife, the mother was to be burnt; according to the Targum of Jonathan, they were to be burnt by pouring lead into their mouths: and so the manner of burning is described in the Misnah (g); they that are to be burnt are fixed in dung up to their knees, then they put a hard napkin within a soft one, and roll it about is neck; one draws it one way, and another another way, until he opens his mouth; then they take hot melted lead, and pour it into his mouth, which goes down into his bowels and burns them. But it was rather done with faggots, of which an instance is given:

that there be no wickedness among you; of such kind, continued, countenanced, and pass unpunished. This punishment was to be inflicted, to deter persons from it. The law against it is in Leviticus 18:17.
