1 Kings 21:10

10 and send ye (in) privily two men, the sons of Belial, against him, and say they (this) false witnessing, Naboth hath blessed God, and the king , that is, hath cursed; and lead ye out him, and stone ye him, and die he so. (and privately, or stealthily, send ye in two men, the sons of Belial, opposite him, and then say they this false witness against him, Naboth hath cursed God, and the king; and then lead ye him out, and stone ye him, and so he shall die.)

1 Kings 21:10 Meaning and Commentary

1 Kings 21:10

And set two men, sons of Belial, before him, to bear witness
against him
Worthless wretches, that have cast off the yoke of the law, as Belial signifies, lawless abandoned creatures, that have no conscience of anything; "knights of the post", as we call them, that will swear anything; these were to be set before Naboth, right against him to confront him, and accuse him to his face, and charge him with crimes next mentioned:

saying, thou didst blaspheme God and the king:
and so was guilty of death for the former, if not for both, and of confiscation of estate for the latter, which was the thing aimed at; and Jezebel was willing to make sure work of it, and therefore would have him accused of both:

and then carry him out, and stone him, that he die;
immediately, without requiring the witnesses to give proof of their charge, and without giving Naboth leave to answer for himself.

1 Kings 21:10 In-Context

8 Therefore she wrote letters in the name of Ahab, and sealed those with the ring of him; and she sent to the greater men in birth, and to the best men, that were in the city of Naboth, and dwelled with him (and she sent them to the men of great age, that is, to the elders, and to the best men, who lived in the city of Naboth with him).

9 And this was the sentence of the letter(s); Preach ye fasting, and make ye Naboth to sit among the first men of the people;

10 and send ye (in) privily two men, the sons of Belial, against him, and say they (this) false witnessing, Naboth hath blessed God, and the king , that is, hath cursed; and lead ye out him, and stone ye him, and die he so. (and privately, or stealthily, send ye in two men, the sons of Belial, opposite him, and then say they this false witness against him, Naboth hath cursed God, and the king; and then lead ye him out, and stone ye him, and so he shall die.)

11 Therefore his citizens, the greater men in birth, and the best men that dwelled with him in the city (And so his fellow citizens, the men of great age, that is, the elders, and the best men who lived with him in the city), did as Jezebel had commanded [to them], and as it was written in the letters, which she had sent to them.

12 They preached fasting, and made Naboth to sit among the first men of the people;
