Jeremiah 7:9

Will ye steal, murder, and commit adultery, and swear falsely, and burn incense unto Baal, and walk after other gods whom ye know not;

The verse lists stealing, murder, adultery, swearing falsely, burning incense to Baal, and walking after other gods whom the people have not known. These acts are grave covenant unfaithfulness that are incompatible with trusting in God and with claiming to serve Him. It exposes the hypocrisy of committing these evils and then coming to the temple claiming safety and deliverance, treating temple worship as protection that excuses wrongdoing and leaves the people free to persist and continue in it. Religious worship and confidence in the temple cannot excuse this course or shield it from punishment and judgment; God sees the conduct, and unfaithfulness brings harm and calamity if left unchecked, so the people must amend their ways, obey God, and abandon false assurances of security.

Judah's trust that temple worship would protect them from judgment repeats Israel's earlier error of trusting the ark to guarantee victory despite sin. The warning applies to people entrusted with responsibility who disregard God's principles, forget the simplicity of His work, and follow the imagination of their own hearts. They rely on their own judgment instead of divine wisdom and power, and give themselves to selfish aims instead of self-denial and self-sacrifice. It applies specifically to church leaders who reject correction, remain proud, and persist in a wrong course; while such conduct governs their actions, God cannot prosper the church.
