1 Kings 21:15

And it came to pass, when Jezebel heard that Naboth was stoned, and was dead, that Jezebel said to Ahab, Arise, take possession of the vineyard of Naboth the Jezreelite, which he refused to give thee for money: for Naboth is not alive, but dead.

Jezebel ... said ... Arise, take possession. Naboth's execution having been announced, and his family being involved in the same fatal sentence (2 Kings 9:26) his property became forfeited to the crown, not by law, but by traditionary usage (see the notes at 2 Samuel 16:4).
