C. F. Keil and Franz Delitzsch on 1 Kings 21:14-15

1Ki 21:14-15

When the report of Naboth’s execution was brought to her, she called upon Ahab to take possession of his vineyard (רשׁ = רשׁ, Deu 2:24). As Naboth’s sons were put to death at the same time, according to 2Ki 9:26, the king was able to confiscate his property; not, indeed, on any rule laid down in the Mosaic law, but according to a principle involved in the very idea of high treason. Since, for example, in the case of blasphemy the property of the criminal was forfeited to the Lord as cherem (Deu 13:16), the property of traitors was regarded as forfeited to the king.
