Even the most reputable among God’s people are capable of error and deceit, and those who claim to speak for the LORD but teach falsehood ultimately undermine the very foundation of faith.
“The head is the elder and honorable man, And the prophet who teaches falsehood is the tail.” (Isaiah 9:15). In this passage, the prophet Isaiah (active roughly between 739 BC and 681 BC) speaks to the nation of Judah, using vivid imagery to describe the corrupt condition of its leadership. By portraying the “head” as the respected civic leaders and the “tail” as the deceitful prophets, Isaiah emphasizes that corruption pervaded society from top to bottom. Those in power, meant to guide the people in righteousness, instead led them astray with worldly wisdom, while false prophets compounded the problem by promoting soothing but deceptive messages rather than confronting sin.
The specific phrase, “the prophet who teaches falsehood is the tail,” underscores the seriousness of spiritual deception during Isaiah’s time. A prophet was supposed to speak truth from God, offering moral clarity and direction. When a prophet turns to falsehood, it becomes a betrayal of a sacred duty. In other biblical contexts, false teachers or “teachers of falsehood” are portrayed as misleading leaders who do not offer godly guidance but instead provide empty promises or rationalize sin. Such a spiritual distortion dishonors God and harms the community (see also the concept of a “teacher of falsehood” in other scriptural passages, where idols and false claims lead people astray).
This verse lays bare the weighty consequence of misguided leadership. Because these honorable men—figures expected to uphold justice—were saturated with pride or complacency, they forfeited their role as a moral compass; and because the prophets taught lies, the people wandered further from genuine worship of the LORD. The dual failure of elders and prophets would soon bring about divine judgment, pointing to a theme repeated throughout Isaiah: true faith requires faithful leadership, and corruption in that leadership profoundly affects everyone under its influence.
