Lessons on betrayal from Joab's actions?
What can we learn about betrayal from Joab's actions in this verse?

The Verse in Focus

2 Samuel 20:10: ‘Amasa was not on his guard against the sword in Joab’s hand, and Joab struck him in the stomach with it, spilling his intestines to the ground. Without needing to strike him again, Amasa was dead. Then Joab and his brother Abishai pursued Sheba son of Bichri.’”


What Betrayal Looked Like That Day

- A friendly embrace turned lethal (see v. 9); Joab’s kiss of greeting mirrored Judas’ kiss centuries later (Luke 22:47-48).

- The treachery was sudden, but the resentment was old. Joab had already murdered Abner in similar fashion (2 Samuel 3:27).

- A single stroke accomplished what Joab wanted: removal of a rival and restoration of his own command.

- David’s direct order (v. 4) was ignored; Joab’s ambition trumped loyalty to the king.


Roots That Fed Joab’s Treachery

1. Jealousy of lost position—Amasa had replaced him (2 Samuel 19:13).

2. Unchecked anger—earlier bloodguilt never repented (1 Kings 2:5-6).

3. Pragmatism over principle—“the end justifies the means” attitude.

4. Hard heart toward God’s law—Numbers 35:30 condemned premeditated murder.

5. Habitual pattern—when sin is not confronted, it becomes easier to repeat.


Timeless Lessons for Our Hearts

- Betrayal often comes from those closest to us (Psalm 55:12-14; John 13:18).

- Outward warmth can mask inner malice; “the kisses of an enemy are deceitful” (Proverbs 27:6).

- Personal ambition easily rationalizes sin when we forget that “promotion comes from the Lord” (Psalm 75:6-7).

- Ignoring authority God has placed over us is the first step toward disloyalty (Romans 13:1-2).

- Hidden grudges, if not confessed, will surface in destructive ways (Hebrews 12:15).

- God sees every covert act; Joab’s crimes eventually met justice through Solomon (1 Kings 2:28-34).

- Betrayal injures more than the victim; it fractures the unity God desires for His people (Ephesians 4:3).


Wise Safeguards Moving Forward

- Guard your heart daily—pray Psalm 139:23-24, inviting God to expose hidden motives.

- Keep short accounts—confess grudges before they fester (1 John 1:9).

- Submit to God-ordained authority even when it feels unfair, trusting His timing (1 Peter 2:13-17).

- Value integrity above advancement; “better is a poor man who walks in integrity than a rich man who is crooked in his ways” (Proverbs 28:6).

- Surround yourself with truthful friends who will confront you in love (Proverbs 27:17).

- Remember the cross—our Lord absorbed humanity’s ultimate betrayal to offer forgiveness; those forgiven much must also forgive (Ephesians 4:32).
