King James wording
King James Version
Take ye heed every one of his neighbour, and trust ye not in any brother: for every brother will utterly supplant, and every neighbour will walk with slanders.THE KEY
The word for “supplant” carries the heel-root, making betrayal a move from behind that takes another’s place.
THE MEANING
Here, brotherhood does not guarantee trust, and a close neighbor can carry harm through words. The verse gives no comforting exception: betrayal can become a pattern around a person, reaching through both relationship and speech.
WHAT THIS UNDOES
It undoes the belief that closeness by itself guarantees safety or trustworthiness.
THE ROOT
עָקֹב יַעְקֹב
ʿāqōḇ yaʿqōḇ
GROWS FROM
עקב
Heel; by extension, following at the heel, overreaching, or supplanting.
“overreach” in this verse is ʿāqōḇ yaʿqōḇ. The Hebrew intensifies the action by repeating this root: the brother will surely supplant. Its heel-image makes betrayal feel like a move from behind, one that displaces another.
ALSO GROWS
ʿāqēḇ: The heel, the back part of the foot.
עָקֵב
This is the root’s concrete image, behind the verse’s language of a concealed move that displaces someone.
Yaʿăqōḇ: Jacob, a name linked in Genesis 27:36 with supplanting.
יַעֲקֹב
That verse makes the heel-root wordplay explicit, giving Jeremiah’s repeated verb a name-shaped echo.
רָכִיל
rākîl
GROWS FROM
רכל
A word-family associated with going about and trafficking; רָכִיל names one who carries tales.
“walk about with slander” in this verse is rākîl. The neighbor is described as going about as a talebearer, so the harm lies in words circulating between people. English “slanders” can hide that picture of speech carried from person to person.
ALSO GROWS
rākal: To travel about or trade.
רָכַל
Its association with going about illuminates the motion in the verse: harmful talk travels through the neighborhood.
rəḵullāh: Trade, traffic, or merchandise.
רְכֻלָּה
This related noun preserves the family’s sense of material being carried and exchanged, echoing how slander circulates.
הִשָּׁמֵרוּ
hiššāmərū
GROWS FROM
שמר
To keep, guard, or watch over.
“Keep watch” in this verse is hiššāmərū. The verse opens with the language of keeping watch, not a vague cue for caution. It holds guarding and trust in tension: a neighbor is near, yet nearness no longer guarantees safety.
ALSO GROWS
shōmēr: One who watches or guards.
שֹׁמֵר
The watchman carries the same active guarding in the verse’s opening command.
mishmeret: A watch, charge, or duty of keeping guard.
מִשְׁמֶרֶת
This branch shows shamar as sustained keeping, giving weight to the verse’s call to watch over oneself.
THE PATTERN
When betrayal enters close relationships, kinship and familiarity can become channels for harm.
Do not lean your weight on a companion; do not lean your full weight upon the familiar one. Guard the doors of your mouth from her who lies against your bosom.Even the man of my wholeness, upon whom I leaned my weight, eats my bread and lifts his heel against me.Brother will hand brother over to death, and father his child; and children will rise up against parents and cause them to die.THE THREAD
And he said, Is he not rightly named Jacob, the heel-grasper? For he has grasped my heel these two times. He took away my birthright, and look, now he has taken away my blessing. And he said, Have you not kept back a blessing for me?Genesis uses the same heel-root word for supplanting and explicitly links it to Jacob’s name. Jeremiah repeats that root for what a brother does, extending the name’s wordplay into a pattern of betrayal.
