The missing letter
To show the seal belonged to Queen Jezebel, Dr. Korpel had to address one crucial matter: The seal reads YZBL, whereas Jezebel's name was known to begin with aleph, the first letter of the Hebrew alphabet. By comparing the seal with similar signets from the same historical period, Korpel showed that seals commonly carried two letters on the top part - precisely where Jezebel's seal was missing a small piece. In keeping with the known pattern from other seals, the first missing letter is almost certainly the possessive lamed. This means the seal probably carried one other letter - the first letter of the owner's name.
