Jeremiah 9:4Meaning & Commentary from the Church Fathers

Let every man take heed of his neighbour, and let him not trust in any brother of his: for every brother will utterly supplant, and every friend will walk deceitfully.

The Church Fathers on this verse

4 Church Fathers comment on this verse

John Chrysostom

4th centuryChurch Father

Let everyone be cautious regarding their own genuine intentions. Consider the profound evil in failing to trust, especially in times of separation from loved ones. This illustrates the devil's intent to sow discord among believers, causing mistrust among brothers, friends, and others we may hold dear. Place not your faith in your companions. In essence, do not rely on anyone, as Christ Himself cautions, "And because lawlessness will abound, the love of many will grow cold" (Matt. 24:12). This does not denote the complete annihilation of friendship, but rather its false appearance. Every brother will stutter in their speech, and individuals will not uphold the truth against one another. In a world overrun by evil, even the tiniest spark of righteousness struggles to emerge.

Gregory of Nyssa

4th centuryChurch Father

Following this, it will be easier for you to grasp the nature of this adversarial mindset, which subtly sets traps into which those who stroll carelessly along the path of life may stumble. Those who, under the pretense of friendship and goodwill, guide their followers into sinful destruction act as ambushers on this journey. They are the ones who seek after shallow praise, lead to frivolous displays, highlight the allure of wrongdoing, and by their actions label themselves as brothers and friends. They repeatedly claim this kinship, despite leading others toward their ultimate demise. It is written about them that “every brother stammereth, and every friend flattereth.”

Ephraem the Syrian

4th centuryChurch Father

Do not place your trust in fellow believers, for even the closest companions may falter. The prophet warns the people to remain vigilant against the treachery of deceivers, whose words are as piercing as arrows and whose speech resembles a bow. They operate not through truth, but through deceit. As stated in the Psalms: their words are like arrows aimed at the unsuspecting heart (Psalm 10:2). This signifies that those who devise wicked schemes dwell in darkness, desiring their trickery to remain hidden. They seek the cover of shadows, or like archers, lay in wait from afar, ensnaring their brethren with flattery, pretense, and crafty language.

Jerome of Stridon

4th centuryChurch Father

Let every individual be cautious of his neighbor and refrain from placing trust in every companion; for all will falter, and every friend will act deceitfully; and each husband will mock his brother, and they will fail to speak the truth. Their tongues have become accustomed to falsehoods; they have grown weary of practicing iniquity and have turned continually away from righteousness. Your dwelling is surrounded by deception; they have chosen to reject knowing Me, says the Lord.

This place is meant for moments of persecution and hardship, marked by a lack of loyalty, when neither brother nor neighbor can be relied upon, and the members of one’s own household become adversaries, akin to what the Gospel states: ‘For a son will betray his father, and a father his son; and they will be divided, three against two, and two against three.’ The phrase, ‘Their tongues have become accustomed to falsehoods,’ signifies that the habit of lying has taken on the character of their very nature, and they earnestly seek to engage in wickedness. The statement, ‘Your dwelling is surrounded by deception,’ suggests that the prophet resides among a treacherous people; or, as the LXX interprets it, 'deceit for deceit,' illustrating that their offenses are ceaselessly piling up, unashamed of past transgressions while committing new ones. In doing so, they strive in every way to disregard the Lord’s commands against such actions.
