What is Joshua's altar on Mount Ebal?

Historical and Scriptural Context

Joshua’s altar on Mount Ebal holds a foundational place in the history recorded in the Old Testament. According to the Berean Standard Bible, shortly after the conquest of Ai, Joshua led the people of Israel to Mount Ebal to build an altar and renew the covenant according to the directives first laid out by Moses. Deuteronomy 27 foretells that once the Israelites entered the Promised Land, they were to stand before Mount Ebal and Mount Gerizim, declaring both curses and blessings. This event is recorded in detail in Joshua 8.

Scripture states:

“Then Joshua built an altar to the LORD, the God of Israel, on Mount Ebal, as Moses the servant of the LORD had commanded the Israelites. He built it according to what is written in the Book of the Law of Moses—an altar of uncut stones on which no iron tool had been used. And on it they offered burnt offerings to the LORD, and sacrificed peace offerings.” (Joshua 8:30–31)

Construction and Significance

The altar’s construction was unique in that the stones were uncut. Moses had relayed the divine command that no iron tool was to be used (Deuteronomy 27:5–6). This method symbolized the Israelites’ submission to God’s instructions, underscoring that the altar’s holiness depended on God’s stipulations, not human craftsmanship.

Mount Ebal was where the curses of the covenant were to be pronounced, in contrast to Mount Gerizim, where the blessings were proclaimed (Deuteronomy 27:11–13). By building an altar on Ebal—the mountain associated with curses—the text illustrates that reconciliation and atonement for sin are provided by the sacrificial system that looked forward, ultimately, to the perfect atoning sacrifice.

Covenant Reaffirmation and Worship

After defeating Ai, Joshua led the nation to publicly reaffirm the covenant. They wrote the law on stones, read the words of the Law of Moses in the presence of the entire assembly—including women, children, and foreigners (Joshua 8:32–35). Hence, the altar served not merely as a place of sacrifice, but as a monumental sign of renewed commitment to the Law.

This reaffirmation took place early in Israel’s settlement of the Promised Land, demonstrating that worship, communal obedience, and covenant faithfulness held priority over military progress or territorial expansion. It showed the people that dependence on God’s instruction was the basis for receiving blessings in the land.

Archaeological Discoveries

Archaeologist Adam Zertal led excavations on Mount Ebal in the 1980s. These digs uncovered a structure dating to the Early Iron Age that some believe aligns with Joshua’s altar:

• A rectangular, podium-like structure with surrounding walls and ramps, which differs from typical Canaanite or later Israelite structures.

• Evidence of animal bones, possibly from sacrificial offerings.

• Uncut stones and signs consistent with an altar-like functionality.

Some scholarly debate remains as to whether this specific site correlates precisely with Joshua’s altar. However, the structure’s existence and the artifacts found there lend strong plausibility to the biblical account. The location and design match well with the sacrificial practices described in Scripture, offering external corroboration of the narrative in Joshua.

Theological Implications

1. Obedience to Divine Command: By building the altar exactly as prescribed—using uncut stones and following God’s instructions—Joshua typifies obedience to God’s Word. It points to the principle that worship must align with God’s revealed will.

2. Symbol of Consecration: The altar on Mount Ebal underscores the biblical theme that atonement for sin is at the heart of humanity’s fellowship with God. The burnt offerings and peace offerings highlight the pursuit of reconciliation and worship.

3. Community Covenant Witness: All Israel participated in hearing the Law and observing the sacrifices. This communal aspect suggests that faith and covenant commitment were never meant to be purely internal or private. Public worship and declaration of God’s words were considered vital for societal identity.

4. Consistency of Scriptural Record: Archaeological evidence, combined with the textual consistency of Deuteronomy 27 and Joshua 8, sustains the reliability of the Old Testament’s historical accounts. Such continuity supports the broader claim that Scripture, from Genesis through Revelation, testifies coherently to God’s redemptive plan.

Connections to the Broader Biblical Narrative

This altar event looks forward beyond the immediate historical context. The sacrificial offerings served as a foreshadowing of a final, once-for-all atoning sacrifice. Although the altar on Mount Ebal was part of the Mosaic sacrificial system, it anticipates the later teachings of the prophets and prepares for the greater work eventually accomplished in the New Testament.

The covenant affirmation on Ebal—where curses for sin were proclaimed—foreshadows how Christ would bear the penalty for sin for all who trust in Him. In this sense, the physical altar on Mount Ebal is a stage in the unfolding story of redemption.

Concluding Summary

Joshua’s altar on Mount Ebal stands as a defining moment in Israel’s history, both archaeologically and biblically. Formed in exact obedience to God’s commands, it represents a crucial pivot in the Israelite settlement of the Promised Land, where the community rededicated itself to the covenants of Moses. Archaeological findings on Mount Ebal offer compelling support for the biblical narrative, aligning with the scriptural details preserved in the Book of Joshua.

Together with the public reading of the Law and communal worship, Joshua’s altar reminds believers that faithful obedience directly correlates to covenant blessing. It remains a vivid emblem of the unity and consistency of God’s revelation, instructing future generations to revere His Word and trust in His redemptive plan.
