The offender may already have been pronounced guilty by the rulers (see Exodus 18:21-22), and the case was referred to Moses in order that the punishment might be awarded by the divine decree. No law had as yet been enacted against blasphemy except by implication. See Exodus 21:17; Exodus 22:28.

And they put him in ward,.... In some prison, a place known in the camp, as Aben Ezra observes:

that the mind of the Lord might be shewed them; for, though this was a breach of the third command, in which God declares he would not hold such an one guiltless, Exodus 20:7; yet no particular punishment being expressed, it was not a clear case whether the Lord would punish for it himself, by an immediate stroke of his hand, or whether by the civil magistrate; and if by the latter, in what manner; for though it might be concluded, without any hesitation, that he was worthy of death, since cursing father or mother was death, Exodus 21:17; and much more blaspheming God, yet what death to put him to they might be at a loss about; or if that was understood of stoning, they might think this deserved a sorer punishment, and therefore consulted God about it.

And they put him in ward, that the mind of the LORD might be showed them.

24:12 That the mind of the Lord might be shewed - For God had only said in general, that he would not hold such guiltless, that is, he would punish them, but had not declared how he would have them punished by men.

that...: Heb. to expound unto them according to the mouth of the LORD

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.
