Ahithophel's counsel was legendary, once considered "as if one inquired of the oracle of God." But when that wisdom turned against God's anointed king, it became dangerous.
Godly Wisdom vs. Human Schemes
Ahithophel's advice in 2 Samuel 16:23 was so highly regarded that "all the counsel of Ahithophel was as if one had inquired of the oracle of God." This means his counsel was sought after and highly valued, often proving correct. However, his allegiance had shifted.
When his wisdom is now directed towards destroying David, it's no longer aligned with God's purposes. This is a critical reminder: wisdom, detached from righteousness and loyalty to God, can become a tool for destruction. True wisdom is always rooted in obedience to God and His will.
