Hebrew Words for Strength

Hebrew has a rich vocabulary for strength — each word carrying distinct nuances from physical power to spiritual courage. Explore the words, their biblical roots, and the names they inspire.

1.

Koach

/KO-akh/

Strength / Power / Force

כֹּחַ
Noun (masculine) · Root: כ-ח

In the Hebrew Bible

One of the most common Hebrew words for strength. Found over 120 times in the Hebrew Bible. God tells Joshua "Chazak ve'ematz" (Be strong and courageous) using a related root. The phrase "b'kol koach" (with all one's strength) appears in the Shema's instruction to love God "with all your might."

Cultural Significance

"Yasher Koach" (יישר כוחך), literally "may your strength be directed," is said to someone who has performed a mitzvah or been called to the Torah. It is one of the most commonly heard Hebrew phrases in synagogue life.

הַתּוֹרָה נוֹתֶנֶת כֹּחַ

The Torah gives strength.

Gevurah

/geh-voo-RAH/

Strength / Might / Heroism / Courage

גְּבוּרָה
Noun (feminine) · Root: ג-ב-ר

In the Hebrew Bible

Derived from the root meaning "to prevail" or "to be mighty." In Psalms 20:7, David declares trust not in chariots but in God's strength. The "Gibborim" (mighty ones) of David were his elite warriors.

Cultural Significance

Gevurah is the fifth of the ten Sefirot in Kabbalah, representing divine judgment, discipline, and restraint. In Pirkei Avot 4:1, Ben Zoma asks: "Who is strong (gibor)? One who conquers their own inclination" — redefining strength as inner mastery rather than physical power.

גְּבוּרָה אֲמִתִּית הִיא שְׁלִיטָה עַצְמִית

True strength is self-mastery.

Oz

/OHZ/

Strength / Boldness / Might / Splendor

עֹז
Noun (masculine) · Root: ע-ז

In the Hebrew Bible

Found throughout the Psalms and Proverbs. Psalm 29:11 reads: "The Lord will give Oz (strength) to His people; the Lord will bless His people with peace." In Proverbs 31:25, the Woman of Valor is described: "Oz v'hadar levushah" — strength and dignity are her garments.

Cultural Significance

Oz is both a standalone Hebrew name and an element in compound names like Uzziah (עוזיה, "my strength is God") and Uzziel (עוזיאל, "God is my strength"). As a modern Israeli name, Oz conveys boldness and confidence.

עֹז וְהָדָר לְבוּשָׁהּ

Strength and dignity are her garments. (Proverbs 31:25)

Chozek

/KHO-zek/

Strength / Fortitude / Toughness

חֹזֶק
Noun (masculine) · Root: ח-ז-ק

In the Hebrew Bible

From the same root as "chazak" (strong). When God commissions Joshua to lead Israel into the Promised Land, He repeats "Chazak ve'ematz" (Be strong and courageous) three times. The root appears over 290 times in the Hebrew Bible.

Cultural Significance

"Chazak, chazak, v'nitchazek!" (Be strong, be strong, and let us be strengthened!) is proclaimed by the entire congregation when completing the reading of each of the Five Books of Moses. This communal declaration transforms individual strength into collective resilience.

חֲזַק וֶאֱמָץ

Be strong and courageous. (Joshua 1:9)

Eitan

/ay-TAHN/

Strong / Enduring / Firm / Mighty

אֵיתָן
Adjective · Root: א-י-ת

In the Hebrew Bible

In Numbers 24:21, Balaam describes a dwelling place as "eitan" — strong and enduring. The name Ethan the Ezrahite appears in 1 Kings 5:11 as one of the wisest men. Psalm 89, attributed to Ethan, begins: "I will sing of the Lord's steadfast love forever."

Cultural Significance

Eitan is one of the most popular Hebrew boy names in Israel. It conveys the idea of something permanent and unshakeable — like a rock or a deeply rooted tree. The modern Hebrew word for a strong, reliable stream is "nahal eitan" (perennial stream).

אֵיתָן מוֹשָׁבֶךָ

Enduring is your dwelling place. (Numbers 24:21)

Tokef

/TO-kef/

Power / Force / Validity / Strength

תּוֹקֶף
Noun (masculine) · Root: ת-ק-ף

In the Hebrew Bible

While less common in the Bible, the root appears in Esther 9:29 and Daniel 4:8. The Aramaic form "takif" means "mighty" or "powerful."

Cultural Significance

Best known from "Unetaneh Tokef," one of the most powerful prayers in the High Holiday liturgy. The prayer declares the "tokef" (power/significance) of the Day of Judgment: "Who shall live and who shall die, who by fire and who by water." It is among the most emotionally intense moments of the Rosh Hashanah and Yom Kippur services.

וּנְתַנֶּה תֹּקֶף קְדֻשַּׁת הַיּוֹם

Let us declare the mighty holiness of this day.

7.

Azuz

/ah-ZOOZ/

Mighty / Fierce / Intense

עַזּוּז
Adjective · Root: ע-ז

In the Hebrew Bible

An intensified form of Oz. Used in Psalm 24:8: "Who is the King of glory? The Lord, strong and mighty (izuz), the Lord mighty in battle." Isaiah 43:17 uses it to describe military might.

Cultural Significance

The root עז gives Hebrew many words and names related to strength. In modern Hebrew, "azuz" is colloquially used to describe something or someone impressive, powerful, or excellent.

יְהוָה עִזּוּז וְגִבּוֹר

The Lord, strong and mighty. (Psalm 24:8)

Ometz

/OH-metz/

Courage / Bravery / Strength of Heart

אֹמֶץ
Noun (masculine) · Root: א-מ-ץ

In the Hebrew Bible

Paired with "chazak" throughout the Bible. God's command to Joshua includes both: "Chazak ve'ematz" — be strong and be courageous. The root emphasizes moral courage and determination as much as physical bravery.

Cultural Significance

"Ometz lev" (אומץ לב), literally "courage of the heart," is the Hebrew expression for bravery and moral fortitude. It represents the inner strength to do what is right even when it is difficult — a central value in Jewish ethics.

אֹמֶץ לֵב הוּא לַעֲשׂוֹת אֶת הַנָּכוֹן

Courage is doing what is right.

Hebrew Names Meaning Strength

These names derive from Hebrew words for strength. Each one carries the power and meaning explored above.

The Concept of Strength in Hebrew

The Hebrew language has at least eight distinct words for strength, each reflecting a different aspect of power. Where Koach (כח) describes raw physical or spiritual force, Gevurah (גבורה) speaks to heroism and self-discipline. Oz (עז) conveys boldness and might, while Ometz (אומץ) points to moral courage — the strength of heart.

This richness of vocabulary reflects how central the concept of strength is to Jewish thought. The Torah repeatedly commands “Chazak ve'ematz” — be strong and courageous. But the Talmud redefines strength not as domination over others, but as mastery over oneself. In Kabbalah, Gevurah is one of the ten divine attributes, representing judgment, discipline, and the focused power that shapes creation.

These words have given rise to some of the most enduring Hebrew names: Gabriel (“God is my strength”), Ethan (“firm, enduring”), Oz (“strength”), Hezekiah (“God is my strength”), and many more. When a Jewish family chooses a name meaning strength, they are drawing on this deep wellspring of meaning — connecting their child to thousands of years of tradition.
