This verse in the King James

King James wording
Woe unto them that are wise in their own eyes, and prudent in their own sight!

When your own eyes become both the measure and the witness, wisdom turns into a closed room.

This warning meets you wherever your own perspective becomes its own proof. You can hold intelligence and discernment, yet still narrow them when nothing beyond your own judgment can test what you see. The verse names the moment when understanding folds back into self-confirmation.

WHAT THIS UNDOES

The lie is that certainty about your own judgment proves that your judgment is clear.

נְבֹנִים

nevonim

GROWS FROM

ב־י־ן

b-y-n

To distinguish, understand, or discern.

“discerning” in this verse is nevonim. The word carries the sense of understanding that can distinguish between things. Set beside “in their own sight,” it shows discernment confined to a self-made frame: the capacity to see distinctions remains, but the self supplies the only measure.

ALSO GROWS

binah: understanding or discernment

בִּינָה

It shares the root’s sense of understanding through distinction, clarifying the depth carried by “prudent.”

bein: between or among

בֵּין

Its relation to the root’s sense of distinguishing gives discernment a relational shape: seeing what lies between or differs.

חֲכָמִים

chachamim

GROWS FROM

ח־כ־ם

ḥ-k-m

To be wise or skillful.

“wise” in this verse is chachamim. The verse does not discard wisdom; it names where these people locate it: “in their own eyes.” The root’s connection to skill makes the warning sharper: real capacity can still be enclosed by the one who claims to possess it.

ALSO GROWS

chokhmah: wisdom or skill

חָכְמָה

It names the quality attributed to them, while the verse questions the self-made standard by which they assess it.

chacham: wise or skillful

חָכָם

This related form keeps the focus on a real capacity whose limits become visible when it answers only to itself.

Discernment narrows when the self becomes its own unquestioned measure.

Do not be wise in your own eyes. Be in awe of the LORD, and turn aside from harm.
Proverbs 3:7 · SDVThe same image names self-assessed wisdom as a place where clear seeing can fail.
Hold the same mind toward one another. Do not set your minds on heights, but be carried along with the lowly. Do not be wise in your own sight.
Romans 12:16 · SDVThe verse places self-regard beside a shared life, where wisdom is no longer measured by the self alone.
Let no one deceive himself. If anyone among you seems to be wise in this age, let him become a fool, that he may become wise.
1 Corinthians 3:18 · SDVIt links self-deception to the appearance of wisdom and opens a way for that closed judgment to be undone.
Therefore, behold, I will add again to do a wonder among this people, even a wonder and a marvel; for the wisdom of their wise ones will lose its way, and the discernment of their discerning ones will be hidden.
Isaiah 29:14 · SDV

The same Hebrew word families for “wise” and “prudent” return here: ⁨חָכָם⁩ (chacham), wise or skillful, and ⁨בִּינָה⁩ (binah), understanding or discernment. The paired roots show how wisdom and discernment can disappear from view when the self-contained judgment that claims them is exposed.
