IT LOOKS LIKE ONE WORD! The Siloam Inscription and the Lachish Letters are considered Classic or Standard Biblical Hebrew. The pictured Lachish letter, dating from c. 589 B.C.E., comes from a collection of letters—written on potsherds—found at Lachish, Israel. The Lachish letters date to the reign of Zedekiah, the last king of Judah.
