Joab's actions: trust lessons?
What can we learn about trust from Joab's actions in this passage?

Key Verse

“​​When Joab left David, he sent messengers after Abner, and they brought him back from the well of Sirah; but David was unaware of it.” — 2 Samuel 3:26


Setting the Scene

• David has just made peace with Abner, Saul’s former commander.

• Joab still burns with resentment because Abner killed Joab’s brother Asahel (2 Samuel 2:23).

• Acting behind David’s back, Joab lures Abner into a private meeting and murders him (v. 27).

• David’s good‐faith trust in Joab and Abner is shattered, exposing several layers of misplaced or abused trust.


What Joab’s Actions Reveal about Trust

• Trust can be violated by private agendas

– Joab presents himself as David’s loyal general yet secretly pursues personal vengeance.

• Human trust is fragile and limited

– Even a king cannot see every motive; David’s ignorance underscores how incomplete our knowledge is.

• Bitterness corrodes judgment

– Joab lets past hurt dictate present action, illustrating Proverbs 14:30, “A tranquil heart is life to the body, but envy is rottenness to the bones.”

• Authority deserves respect, not manipulation

Romans 13:1 teaches submission to governing authority; Joab’s subversion shows the danger of acting outside rightful channels.

• Retribution belongs to God, not to us

Romans 12:19: “Beloved, do not avenge yourselves, but leave room for God’s wrath, for it is written: ‘Vengeance is Mine; I will repay, says the Lord.’ ” Joab seizes a role reserved for God alone.


Lessons for Trusting Wisely

• Anchor ultimate trust in the Lord, not in even the most dependable people

Psalm 118:8: “It is better to take refuge in the LORD than to trust in man.”

• Test choices against Scripture, not personal emotion

Proverbs 3:5-6 tells us to lean not on our own understanding. Joab leans entirely on wounded pride.

• Keep short accounts with others

Ephesians 4:31-32 urges believers to put away bitterness, because unresolved grievances distort discernment.

• Maintain transparency

– Joab acts in secrecy; Christ calls His followers to walk in the light (John 3:21).

• Value accountability

– David’s later public lament (2 Samuel 3:28-39) counters Joab’s clandestine deed, signaling that godly leadership brings actions into the open.

• Guard entrusted influence

– Joab’s high position magnified the fallout. Luke 12:48: “From everyone who has been given much, much will be required.”


Supporting Passages

Jeremiah 17:5-7 contrasts the curses of trusting flesh with the blessing of trusting the Lord.

Psalm 146:3-5 warns not to trust in princes “in whom there is no salvation.”

1 Peter 2:23 models how Jesus “entrusted Himself to Him who judges justly,” choosing God’s justice over personal retaliation.


Practical Takeaways

• Place first trust in God’s unchanging character; hold human trust loosely and wisely.

• Examine motives before acting, ensuring they align with God’s Word rather than personal hurt.

• Cultivate openness and invite counsel to prevent secret agendas from taking root.

• Remember that position and power amplify consequences; steward influence with humility.

• When wronged, release vengeance to God, knowing His justice is perfect and timely.
