'Letter' in the Bible

So she sent a letter in Ahab's name, stamped with his stamp, to the responsible men and the chiefs who were in authority with Naboth.

And in the letter she said, Let a time of public sorrow be fixed, and put Naboth at the head of the people;

So the responsible men and the chiefs who were in authority in his town, did as Jezebel had said in the letter she sent them.
