Why is the testimony of one witness insufficient according to Deuteronomy 19:15?

Understanding Deuteronomy 19:15

“​A lone witness is not sufficient to establish any wrongdoing or sin against a man, regardless of the offense; a matter must be established by the testimony of two or three witnesses.” (Deuteronomy 19:15)

The Two-or-Three Witness Principle

• God requires corroboration—two or three witnesses—to confirm any accusation.

• This standard safeguards justice and truth in Israel’s courts.

• It becomes a recurring biblical pattern, echoed by prophets, Jesus, and the apostles.

Why a Single Witness Is Insufficient

• Human fallibility

- Memory can fade or be selective (Jeremiah 17:9).

- Perception can be limited or biased.

• Protection against false accusation

- One malicious person could ruin an innocent life (Exodus 23:1).

• Upholding God’s character of justice

- “Righteousness and justice are the foundation of Your throne” (Psalm 89:14).

- God’s justice requires reliable evidence, not hearsay.

• Promoting communal responsibility

- Multiple witnesses involve the community in discerning truth.

• Foreshadowing higher standards

- Points to Christ’s call for verifiable testimony in church discipline (Matthew 18:16).

Scripture Echoes of the Same Standard

• Numbers 35:30—capital cases require at least two witnesses.

• Matthew 18:16—Jesus cites Deuteronomy when addressing sin in the church.

• John 8:17—Jesus appeals to “the testimony of two men” in defending His claims.

• 2 Corinthians 13:1—Paul applies the rule to church disputes.

• 1 Timothy 5:19—elders may be accused only with two or three witnesses.

Practical Applications Today

• Seek corroboration before forming judgments.

• Reject gossip that relies on a single source.

• Build church discipline and accountability on verifiable evidence.

• Honor God’s justice by ensuring fairness in families, workplaces, and courts.

Closing Reflection
