Joab vs. Bible on honesty integrity?
How does Joab's behavior compare to biblical teachings on honesty and integrity?

Setting the Scene

2 Samuel 20:9 records, “Joab said to Amasa, ‘How are you, my brother?’ Then Joab grasped Amasa by the beard with his right hand to kiss him.”

• The context shows Amasa had been appointed commander in Joab’s place (2 Samuel 19:13). Joab, fearing loss of power, greets Amasa as a friend, but in the next verse fatally stabs him.

• Joab’s words and gesture are outwardly friendly; his heart is murderous. The contrast between appearance and intent is the heart of the integrity issue.


Joab’s Deceptive Greeting

• Friendly greeting: “How are you, my brother?”

• Cultural sign of respect: grasping the beard for a kiss.

• Hidden motive: assassination.

• Joab weaponizes trust; his right hand promises peace while concealing a sword in the left (v.10).


Scripture’s Call to Honest Speech

Exodus 20:16 — “You shall not bear false witness.”

Leviticus 19:11 — “You must not steal, lie, or deceive one another.”

Proverbs 12:22 — “Lying lips are detestable to the LORD, but those who act faithfully are His delight.”

Ephesians 4:25 — “Therefore each of you must put off falsehood and speak truthfully to his neighbor.”

Joab’s greeting is a lie in motion; every one of these commands exposes his sin.


Integrity Versus Expediency

Scripture repeatedly lifts integrity above self-interest:

Psalm 15:2 — “He who walks with integrity, who practices righteousness and speaks the truth from his heart.”

Proverbs 20:7 — “The righteous man walks with integrity; blessed are his children after him.”

Joab chooses expediency—retaining command—over righteousness. He steps outside the protective boundaries of God’s law, placing personal ambition above divine principle.


Echoes of Betrayal

• Joab’s feigned kiss foreshadows Judas’s kiss in Matthew 26:48-49. Both men:

– Address the victim as “friend/brother.”

– Use an affectionate gesture to mask betrayal.

– Serve self-interest while pretending loyalty.

The pattern underlines the timeless warning: deceitful intimacy violates God’s heart.


Consequences of Deceit

Proverbs 6:16-19 lists “a lying tongue” and “hands that shed innocent blood” among the seven things the Lord hates—precisely Joab’s actions.

• Joab avoids immediate earthly justice, but 1 Kings 2:5-6, 28-34 shows his violent record eventually leads to his execution under Solomon.

Numbers 32:23 reminds, “Be sure your sin will find you out.”


Walking in Truth Today

Joab’s story presses believers toward transparent lives:

• Align words and motives; let a greeting mean what it says.

• Guard positions of influence—never cling to them by manipulation.

• Remember integrity is measured when gain is on the line.

• Fill speech with grace and truth (Colossians 4:6).

• Trust God’s timing for promotion (Psalm 75:6-7), instead of seizing it through deceit.

Joab’s behavior stands in stark opposition to the Bible’s unambiguous call to honesty and integrity. His example warns that duplicity, no matter how skillful, collides with the God who “desires truth in the inmost being” (Psalm 51:6).
