1 Kings 21:8

So she wrote letters [Heb. writings ] in Ahab's name, and sealed them with his seal [The use of the seal, for the purpose of authentication, is of great antiquity. Some of the Egyptian signets are more than 4,000 years old. Their use in the age of the patriarchs is attested by Genesis 38:15 and Genesis 41:42 ; their importance is proved by the text, by Esther 3:10 ; Esther 8:2 , Esther 8:8 , Esther 8:10 (cf. "Herod," 3:128); Daniel 6:17 ; Jeremiah 32:10 , 54; Haggai 2:23 , etc. Whether this seal—which does not necessarily prove that those who used it could not write—was impressed upon the writings themselves according to the modern practice of the East, or upon a piece of clay ( Job 38:14 ), which was then attached to the letter by strings, we have no means of knowing. The use of Ahab's seal affords a strong presumption that he was privy to her designs (Bähr), but of this we cannot be absolutely certain], and sent the letters unto the elders [see Deuteronomy 16:18 ] and to the nobles [same word Nehemiah 2:16 ; Nehemiah 4:13 ; Ecclesiastes 10:17 ] that were in his city, dwelling [or inhabitants, as in Ecclesiastes 10:11 ] with Naboth.
