'LMLK seals' (למלך) were stamped on the handles of large storage jars mostly in and around Jerusalem during the reign of King Hezekiah (circa 700 BC) based on several complete jars found in situ buried under a destruction layer caused by Sennacherib at Lachish.
Layard noted in his work that Henry Rawlinson, the "Father of Assyriology", disagreed with the identification as the biblical Lachish.
:After this Sennacherib king of Assyria sent his servants to Jerusalem (but he and all the forces with him laid siege against Lachish), to Hezekiah king of Judah, and to all Judah who were in Jerusalem...
In the Book of Nehemiah (11:30) Lachish is mentioned as an area where the people of Judah settled during the time of the Achaemenid Empire.
