“The ancient and honourable, he is the head; and the prophet that teacheth lies, he is the tail.”
King James Version (KJV)

Read Full Chapter →Positions of honor can carry real responsibility, and religious speech can deeply shape a community. Isaiah 9:15 names both realities in a sentence of judgment. It helps us see why the chapter treats Israel's crisis as more than military pressure: those who should have guided the people were implicated in their moral confusion.
Isaiah identifies the "head and tail" of verse 14: honored elders are the head, and prophets who teach lies are the tail. The verse exposes how both respected status and false religious speech can corrupt a people.
The Context of Isaiah 9:15
After announcing the coming Davidic ruler in verses 6-7, Isaiah records a word of judgment that has come upon Jacob and Israel. Ephraim and Samaria respond to hardship with pride rather than turning to the LORD. Verse 13 states that the people do not seek the LORD of hosts, and verse 14 announces that the LORD will cut off "head and tail, branch and rush, in one day." Verse 15 explains the image: the ancient and honorable are the head, while the prophet teaching lies is the tail. Verse 16 then states the consequence, for leaders cause the people to err and those led by them are destroyed.
What Does Isaiah 9:15 Mean?
The verse explains the two parts of Isaiah's image. "The ancient and honourable" refers to people recognized for age and standing, and Isaiah calls them "the head." Their social prominence gave them weight among the people. "The prophet that teacheth lies" is called "the tail." A prophet was expected to speak a message from God, so teaching lies was a serious betrayal of that calling. The contrast between head and tail does not make the elder innocent or the false prophet insignificant. It identifies different kinds of influential people who stood within a community under judgment. Honor and religious office did not protect them when they participated in the nation's unfaithfulness.
Verse 15 must be read with verses 13-16. The people themselves refuse to turn and seek the LORD, while their leaders contribute to their error. Isaiah therefore neither excuses the people by blaming leaders nor treats leadership as harmless. The chapter portrays a shared moral collapse, with especially grave consequences when guidance is false. The LORD's announced cutting off of head and tail belongs to the judgment described in the surrounding passage. It is a warning against confidence in social rank, age, or a claimed spiritual message when these are separated from truth and faithfulness to God. The following verse underscores the destructive reach of such leadership.
Elsewhere, Scripture calls God's people to test messages that claim divine authority and to value truthful teaching. Jeremiah speaks against prophets who proclaim a vision from their own heart rather than the LORD's mouth. Jesus also warns of false prophets and teaches that they are recognized by their fruits. These connections do not turn Isaiah 9:15 into a license for suspicion toward every teacher or elder. The verse addresses genuine corruption in leadership. It calls for discernment shaped by the LORD's revealed character, humility before correction, and concern for the people who may be harmed when lies are given the appearance of sacred guidance.
Bible Verses Related to Isaiah 9:15
“Therefore the LORD will cut off from Israel head and tail, branch and rush, in one day. The ancient and honourable, he is the head; and the prophet that teacheth lies, he is the tail. For the leaders of this people cause them to err; and they that are led of them are destroyed.”
- Isaiah 9:14-16
“Thus saith the LORD of hosts, Hearken not unto the words of the prophets that prophesy unto you: they make you vain: they speak a vision of their own heart, and not out of the mouth of the LORD. They say still unto them that despise me, The LORD hath said, Ye shall have peace; and they say unto every one that walketh after the imagination of his own heart, No evil shall come upon you.”
- Jeremiah 23:16-17
“And mine hand shall be upon the prophets that see vanity, and that divine lies: they shall not be in the assembly of my people, neither shall they be written in the writing of the house of Israel, neither shall they enter into the land of Israel; and ye shall know that I am the Lord GOD. Because, even because they have seduced my people, saying, Peace; and there was no peace; and one built up a wall, and, lo, others daubed it with untempered morter:”
- Ezekiel 13:9-10
“Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves. Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles? Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit. A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. Wherefore by their fruits ye shall know them.”
- Matthew 7:15-20
Where Isaiah 9:15 Echoes in Scripture
Jeremiah 23:16-17 strongly echoes Isaiah's concern about prophets who teach what is false. Jeremiah warns the people not to listen to prophets whose messages arise from their own heart and who promise peace without the LORD's warrant. Like Isaiah 9:15, the passage treats false prophecy as a public danger, because it directs people away from repentance and truthful dependence on God.
How to Apply Isaiah 9:15 Today
We can receive this verse as an invitation to practice careful discernment without contempt. Respect for experience, education, office, or a confident religious voice has its place, yet none of these removes the need to seek what is true before God. In ordinary life, that can include reading a passage in context, weighing a claim against the wider witness of Scripture, asking wise questions, and noticing whether teaching leads toward truthfulness, repentance, justice, and love of God. Those entrusted with influence can also remember that their words affect others. Honest limits and faithful correction are acts of care.
