The Bible verse Psalm 36:3 from the King James Version (KJV) states: "The words of his mouth are iniquity and deceit: he hath left off to be wise, and to do good." This verse is a part of a psalm written by King David, and it reflects on the contrast between the wickedness of the ungodly and the righteousness of God.

The theme of this verse centers on the sinful nature of man and the deceptive words that come from their mouth. The psalmist is addressing the conduct of an individual who has rejected wisdom and goodness and instead chooses the path of iniquity and deceit. This verse serves as a warning against ungodly behavior and encourages believers to uphold moral righteousness and truthfulness.

The context of this verse can be found in the broader context of Psalm 36, where David begins by describing the wickedness of the ungodly. He contrasts their sinful ways with the character of God, emphasizing His steadfast love, faithfulness, righteousness, and justice. In verse 3, David specifically addresses the deceptive words and unwise actions of the wicked, highlighting their departure from goodness and wisdom.

The symbolism in this verse lies in the contrast between light and darkness, truth and deceit, wisdom and foolishness. The "words of his mouth" symbolize the expression of one's inner nature, reflecting the heart and character of an individual. Iniquity and deceit represent the sinful and deceptive intentions that guide the speech and actions of the wicked. The abandonment of wisdom and goodness symbolizes a rejection of God's ways and a departure from moral integrity and righteousness.

The use of "left off" in this verse implies a deliberate choice to cease from being wise and doing good, suggesting that the individual has willfully turned away from the path of righteousness and embraced wickedness instead. This reinforces the idea that sin is a conscious decision and reflects the rebellious nature of the human heart.

An important aspect of this verse is its relevance to the human condition. It serves as a reminder that all have sinned and fallen short of the glory of God (Romans 3:23), and that the natural inclination of the human heart is towards evil (Jeremiah 17:9). It underscores the universal need for repentance, redemption, and the transformative power of God's grace.

In Christian theology, this verse also points to the greater redemptive narrative found in the New Testament. It highlights the contrast between the unrighteousness of humanity and the righteousness of God, and underscores the need for a Savior to bridge that gap. Jesus Christ is the ultimate embodiment of wisdom and goodness, and His sacrificial death on the cross provides the way for sinners to be reconciled to God.

In sum, Psalm 36:3 from the King James Version (KJV) is a poignant reflection on the sinful nature of man, the deceptive words that flow from the ungodly, and the contrast between wickedness and righteousness. It serves as a call to moral integrity, wisdom, and truthfulness, and points to the universal need for repentance and the redemptive work of Christ. It offers timeless wisdom and encouragement for believers to uphold the standards of righteousness and to seek God's transformative grace in their lives.
