In excavations in Jerusalem near the U.S. embassy conducted by the Israel Antiquities Authority, more than 120 of some of the largest and most important collections of seal impressions stamped on jars were discovered, revealing information into tax collection in the period of the Judean monarchs some 2,700 years ago.

The impressions were stamped with the letters “LMLK”—meaning “to the King”—and were written in ancient Hebrew script, along with the name of the ancient city in the Kingdom of Judah.

The excavations are funded by the Israel Land Authority and administrated by the Moriah Jerusalem Development Corporation.

Other seals are associated with private individuals and bear the name of senior officials of the Kingdom of Judah or wealthy individuals from the First Temple period.
