(18) And he that killeth a beast.--The law about killing a human being is now followed by the enaetments with regard to killing a beast. He who kills an animal has to make it good by giving another animal for it. The case is not the same as that legislated for in Exodus 21:33-34.
Verses 18-21. - A summary of the law respecting minor injuries is added to that respecting murder. He that killeth a man, he shall be put to death, but he that killeth a beast shall make it good; and this lex talionis shall apply to all damage done to another, breach for breach, eye for eye, tooth for tooth (see Matthew 5:38).
24:10-23 This offender was the son of an Egyptian father, and an Israelitish mother. The notice of his parents shows the common ill effect of mixed marriages. A standing law for the stoning of blasphemers was made upon this occasion. Great stress is laid upon this law. It extends to the strangers among them, as well as to those born in the land. Strangers, as well as native Israelites, should be entitled to the benefit of the law, so as not to suffer wrong; and should be liable to the penalty of this law, in case they did wrong. If those who profane the name of God escape punishment from men, yet the Lord our God will not suffer them to escape his righteous judgments. What enmity against God must be in the heart of man, when blasphemies against God proceed out of his mouth. If he that despised Moses' law, died without mercy, of what punishment will they be worthy, who despise and abuse the gospel of the Son of God! Let us watch against anger, do no evil, avoid all connexions with wicked people, and reverence that holy name which sinners blaspheme.
beast for beast; or "soul for soul"; life for life, that is, a living one for that the life of which is taken away, and one every way as good as that.
