THANKFUL FOR DESTRUCTIVE FIRES. In the world of archaeology, a bulla (or bullae in the plural) is a small, hardened lump of clay used in antiquity to seal documents, written records, or packages. It was done by pressing a lump of wet clay around the knotted cord of a rolled papyrus or parchment, or around the opening of a storage jar. A personal or official seal was then stamped into the clay, signifying its owner.
If the document or container was opened, the clay seal would have to be broken, guaranteeing that the contents had not been tampered with or intercepted.
Only authorized individuals were permitted to break the seal and access the contents it secured (e.g., only Jesus could open the seven-sealed scroll in God’s hand, Revelation 5:1).
Once opened, a bulla was typically discarded, left to be discovered thousands of years later among the ruins of ancient homes and buildings.
Bullae become rock-like when hardened by a destructive fire, preserving them forever along with the precious information they contain.
In these instances, we should be thankful for a destructive fire because some bullae contained a name, a title, and unique iconography. With each seal impression, archaeologists and historians can learn about the past.
They are also invaluable for validating the reliability of scripture and the claims of its writers.
If biblical authors are indeed credible and reliable witnesses to the past, then evidence should be available to corroborate their testimony. If they were truly contemporaries of the period in which they are purported to have written their accounts, then the names, places, events, etc., they record should be consistent with the archaeological data. Indeed, this is the case.
For example, in the 1980s, Yigal Shiloh discovered some 51 bullae in his excavations near the famed “Area G” of the City of David (pictured above). One of the inscriptions read “Gemaryahu ben Shafan,” a man known as King Jehoiakim’s scribe mentioned in the Book of Jeremiah 36:10.
Years later, Eilat Mazar discovered other important bullae at another location near the City of David, revealing the names of two ministers of King Zedekiah mentioned in Jeremiah 38:1, “Yehuchal Ben Shelamayahu” and "Gedaliah Ben Pashchur.” These are two of four ministers who unsuccessfully plotted to kill the prophet Jeremiah (see The Palace of King David, 68, by Mazar).
Some of the most exciting bullae were discovered during the 2009-2013 excavations at Ophel (just south of the Temple Mount).
As reported in a 2015 press release and discussed in several issues of Biblical Archaeology Review (BAR), a bulla bearing Hezekiah’s name was found in an ancient garbage pit near the royal structure of the Ophel excavations. The bulla was among 34 bullae discovered and dated to the Iron Age (1200-586 B.C.).
Yet again, in 2018, another bulla was discovered and believed to be a seal impression of the prophet Isaiah. This additional bulla bears an inscription from the First Temple period that appears to spell the name Yesha’yah[u] (“belonging to Isaiah”).
On a line below, there is the partial Hebrew word “nvy”, which presumably spells “prophet.” This could be a seal impression made by the prophet Isaiah himself. (See Biblical Archaeology Review 2018 March/April, May/June double issue for a full discussion.)
The sheer number of artifacts, such as bullae, inscriptions on stone tablets and walls, potsherds, and silver, that relate to the Bible is very remarkable. In fact, epigrapher Peter Kyle McCarter selected only 140 from a vast storehouse of inscriptions for his well-known book, Ancient Inscriptions: Voices from the Biblical World, and could have included hundreds more.
His book includes information about the Merneptah Stele (a 13th Century B.C. Egyptian monument listing Israel among other nations), the Gezer Calendar (a 10th Century B.C. planting calendar written in an early Hebrew script that reveals the early development of an organized society), the Moabite Stone (a 9th century B.C. victory stela of Moabite King Mesha that confirms 2 Kings 3 and also makes reference to the House of David), and much, much more.
McCarter’s book, along with many others, was among the earliest I encountered when I first began my journey into the wonderful world of archaeology and the Bible.
With each passing year, I stand amazed at the sheer volume of evidence that emerges. It continues to demonstrate the reliability of the biblical record again and again.
