This verse in the King James

King James wording
They that sanctify themselves, and purify themselves in the gardens behind one tree in the midst, eating swine’s flesh, and the abomination, and the mouse, shall be consumed together, saith the LORD.

They set themselves apart and purify themselves, yet those acts do not alter the verdict: they are consumed together.

You meet a sharp distinction here: declaring yourself set apart and clean does not erase what you do. The people in the gardens eat swine’s flesh, the abomination, and the mouse, then are consumed together under the LORD’s pronouncement.

WHAT THIS UNDOES

The lie that a private sacred ritual can make an act clean simply because its participants consecrate themselves.

הַמִּתְקַדְּשִׁים

hammitqaddeshim

GROWS FROM

קדש

q-d-sh

Set apart as sacred.

“those who set themselves apart” in this verse is hammitqaddeshim. The verb is reflexive: they perform the setting apart on themselves. The same root gives qadosh, “set apart,” and miqdash, “sanctuary”; here, that self-consecration sits beside the practices named in the verse and does not shelter them from its ending.

ALSO GROWS

qadosh: Set apart.

קָדוֹשׁ

The adjective names the set-apart quality they claim through their own act.

qodesh: Set-apartness; what is sacred.

קֹדֶשׁ

This noun shows that sanctification is a state of being set apart, not merely a ritual label.

miqdash: Sanctuary; set-apart place.

מִקְדָּשׁ

The same root links personal consecration with a place marked as sacred.

וְהַמִּטַּהֲרִים

vehammitṭahărim

GROWS FROM

טהר

ṭ-h-r

Be clean or pure; cleanse.

“cleanse themselves” in this verse is vehammitṭahărim. This verb is also reflexive: they are purifying themselves. The root names both the act of cleansing and the condition of being clean, but the verse places their claim to purity beside the acts it condemns.

ALSO GROWS

tahor: Clean; pure.

טָהוֹר

The adjective names the state the participants are claiming for themselves.

tahorah: Cleanness; purification.

טָהֳרָה

This noun connects the act of purification to the resulting condition of cleanness.

tiher: Cleansed; purified.

טִהֵר

This verb form makes the root’s cleansing action explicit.

A claim of purity cannot conceal the condition of the life beneath it.

Bathe, and become clear. Remove the harm of your deeds from before my eyes. Let go of doing harm.
Isaiah 1:16 · SDVCleansing is joined to putting away evil actions, so the measure reaches beyond a ritual claim.
Woe to you, writers and separated ones, masked ones! For you make clean the outside of the cup and the dish, but within they are filled from grasping and from what has no grip.
Matthew 23:25 · SDVThe outside can be made clean while the contents remain unchanged, exposing the gap between appearance and the life within.
They say, Do not draw near me, for I am set apart from you. These are smoke in my nostrils, a fire burning all the day.
Isaiah 65:5 · SDV

“Sanctify” in Isaiah 66:17 and “holier” here draw on ⁨קדש⁩ (q-d-sh), the root of being set apart. Isaiah 65:5 exposes the posture of claiming that status over others; Isaiah 66:17 shows self-consecration beside the very acts the verse condemns.
