Sons of Belial - i. e., “worthless persons” (Deuteronomy 13:13 note). Witnesses must be two in number according to the Law Numbers 35:30; Deuteronomy 17:6; Deuteronomy 19:15.
The word rendered “blaspheme” is that which commonly means “bless.” The opposite sense of “cursing,” seems, however, to be required here and in Job 1:5, Job 1:11; Job 2:5. Perhaps the best explanation of the bad sense of the original word is to be found in the practice of blessing by way of salutation, not only on meeting, but also on taking leave Genesis 47:7, Genesis 47:10. From the latter custom the word came to mean “bidding farewell to,” and so “renouncing,” “casting off,” “cursing.”
Carry him out and stone him - Naboth’s offence would be twofold, and in both cases capital; blasphemy against God being punishable with death by the Law (marginal reference), and blasphemy against the king being a capital offence by custom 1Ki 2:8; 2 Samuel 16:9; 2 Samuel 19:21. The punishment would be stoning, since the greater crime would absorb the lesser, and the Law made stoning the punishment for blasphemy against God. As stoning always took place outside the city (see Acts 7:58), Jezebel told the elders to “carry Naboth out.”
