The Lachish Letters (Lachish Ostraca) Reveal the Divine Name of God

Quick Facts

• The Lachish Letters, also known as the Lachish Ostraca or Lachish Ostracon, are among the most important archaeological discoveries relating to the Old Testament.

• They were discovered during excavations at Tell ed-Duweir (ancient Lachish) by James Leslie Starkey in January–February 1935.

• The letters were written in ancient Hebrew using carbon ink on broken pieces of pottery (ostraca).

• They date to around 589–586 BC, shortly before the Babylonian destruction of Judah.

• Most importantly, these remarkable letters contain the divine name of God—YHWH (Yahweh)—demonstrating that God's personal name was in everyday use during the final years of the Kingdom of Judah.

One of the Bible's Greatest Archaeological Discoveries

The Lachish Letters provide an extraordinary glimpse into the final days of the Kingdom of Judah before Jerusalem fell to Babylon.

These letters were written by military officials stationed at the fortified city of Lachish, one of Judah's last remaining strongholds. At this time, the Babylonian army under King Nebuchadnezzar was advancing through Judah, destroying fortified cities one after another before laying siege to Jerusalem.

The letters contain real military correspondence exchanged during this desperate period of biblical history, making them one of the most significant archaeological discoveries confirming the historical setting of the Old Testament.

Even more remarkable is that they repeatedly preserve the sacred name of God:

YHWH (Yahweh).

The Divine Name Appears Clearly

One of the letters reads:

"To my lord, Yaush, may YHWH cause my lord to hear tidings of peace today, this very day! Who is your servant, a dog, that my lord has remembered his servant? May YHWH make known to my lord a matter of which you do not know."

This inscription is remarkable because it demonstrates that faithful Israelites were still freely using God's personal name shortly before Jerusalem was destroyed.

Rather than avoiding the divine name, as later Jewish tradition came to do, the writers naturally referred to God as YHWH.

This provides powerful archaeological evidence that the divine name was widely known and commonly used during the biblical period.

The Lachish Letters Confirm the Bible

The historical setting described in the letters agrees remarkably well with the Book of Jeremiah.

Jeremiah records:

"When the army of the king of Babylon was fighting against Jerusalem and against all the cities of Judah that were left, Lachish and Azekah, for these were the only fortified cities of Judah that remained."
Jeremiah 34:7 (ESV)

This verse perfectly matches the circumstances reflected in the Lachish correspondence.

As Babylon advanced, only a few fortified cities remained standing.

Lachish was one of them.

The Expression "A Dog"

The phrase found in the Lachish Letter:

"Who is your servant, a dog..."

was a common Hebrew expression of humility.

The same expression appears elsewhere in the Scriptures.

David's servant Mephibosheth said:

"What is your servant, that you should show regard for a dead dog such as I?"
2 Samuel 9:8 (ESV)

Abishai said to David:

"Why should this dead dog curse my lord the king?"
2 Samuel 16:9 (ESV)

Likewise, Hazael replied to Elisha:

"But what is your servant, who is but a dog, that he should do this great thing?"
2 Kings 8:13 (World English Bible)

The repetition of this expression in both the Bible and the Lachish Letters beautifully illustrates how authentic these ancient documents are.

The Name Yahweh in the Bible

The World English Bible translates 2 Kings 8:13 as:

"Yahweh has shown me that you will be king over Syria."

This reflects the same divine name found in the Lachish Letters.

The archaeological evidence and the biblical text therefore support one another, both preserving God's covenant name:

YHWH (Yahweh).

Why This Discovery Matters

The Lachish Letters demonstrate that:

• the biblical account accurately describes the final years of Judah;

• Lachish was indeed one of Judah's last fortified cities;

• the Hebrew language used in the Bible matches contemporary inscriptions;

• God's personal name, YHWH, was being written and spoken by faithful Israelites before the Babylonian exile.

These ancient inscriptions provide another powerful piece of archaeological evidence supporting the historical reliability of the Old Testament.

Conclusion

The Lachish Letters are far more than broken pieces of pottery.

They are authentic voices from one of the darkest moments in Israel's history.

Written while Babylon surrounded Judah, they preserve military reports, everyday Hebrew language, and—most significantly—the divine name YHWH (Yahweh).

Nearly 2,600 years later, these remarkable inscriptions continue to testify that the Bible records real people, real places, real events, and the worship of the one true God whose name was known throughout Judah.

As Jesus said:

"Seek, and you will find." (Matthew 7:7)

The more archaeology uncovers the ancient world, the more it continues to illuminate the historical background of the Scriptures and strengthen confidence in the reliability of the biblical record.
