How One Word Built the Western Wall

"הכותל – אזוב ועצבת / הכותל – עופרת ודם; יש אנשים עם לב של אבן / יש אבנים עם לב אדם"

(Yossi Gamzu, HaKotel)

During the Six-Day War, Israeli paratroopers reached the Kotel HaMa'aravi (the Western Wall) – the remaining portion of the western retaining wall surrounding the Temple Mount that survived the destruction of the Second Temple.

The word כותל (Kotel) actually appears only once in biblical Hebrew: "הִנֵּה זֶה עוֹמֵד אַחַר כָּתְלֵנוּ, מַשְׁגִּיחַ מִן הַחַלֹּנוֹת מֵצִיץ מִן הַחֲרַכִּים" (Song of Songs 2:9). On the other hand, its everyday sibling, the word קיר (Kir), appears over seventy times throughout the Bible.

In Aramaic, כותל was the standard word for wall (written as כְּתַל or כֻּתְלָא), and we already see it popping up in the biblical Aramaic sections of Ezra and Daniel. Rabbinic Hebrew (Leshon Chazal) was heavily influenced by Aramaic, so כותל naturally became the go-to word there as well, while קיר was kept mainly for direct references to biblical texts.

For instance, the Sages used the phrase קיר המזבח rather than כותל המזבח, simply because the Bible specifically uses the phrase עַל קִיר הַמִּזְבֵּחַ when discussing the sacrificial blood on the altar. We see the same pattern when the Sages discussed physical walls directly tied to biblical stories:

A person should turn towards the wall to pray. Why? Because it says, "וַיַּסֵּב חִזְקִיָּהוּ פָּנָיו אֶל הַקִּיר" (Isaiah 38:2). But which wall was Hezekiah looking at? Rabbi Yehuda ben Levi suggested he was looking at Rahab's wall, as it says "כִּי בֵיתָהּ בְּקִיר הַחוֹמָה" (Joshua 2:15). Rabbi Samuel bar Nachmani suggested he was looking at the Shunammite woman's wall, as it says "נַעֲשֶׂה נָּא עֲלִיַּת קִיר קְטַנָּה" (2 Kings 4:10).

Fast forward to modern Hebrew: קיר is our everyday, standard word for a wall. Meanwhile, כותל feels a bit more special, elevated, and poetic – likely thanks to its association with the Western Wall. In fact, saying "הכותל" on its own is usually just shorthand for הכותל המערבי.

When engineers, builders, or everyday speakers talk about walls, or when we talk about a wall clock or a wall newspaper, we always use קיר (like שעון קיר, לוח קיר, עיתון קיר) and never כותל.

Hebrew is full of idioms built around walls, and their choice of words usually reveals their origins. Expressions rooted in the Bible stick with קיר, such as קִירוֹת לִבִּי, מַשְׁתִּין בְּקִיר, קיר [ה]ברזל, ללחוץ אל הקיר (inspired by Balaam's donkey in Numbers 22:25: "וַתֵּרֶא הָאָתוֹן ... וַתִּלָּחֵץ אֶל הַקִּיר וַתִּלְחַץ אֶת רֶגֶל בִּלְעָם אֶל הַקִּיר"), and אֶבֶן מִקִּיר תִּזְעָק.

On the flip side, idioms originating from Rabbinic literature lean on כותל, such as אוזניים לכותל, הטיח ראשו בכותל, and of course the famous tradition: לעולם אין השכינה זזה מכותל המערבי.

When it comes to modern Hebrew slang, it’s only natural that the everyday word קיר takes center stage. That's where we get familiar phrases like ראש בקיר, דפק את הראש בקיר, מדבר אל הקיר, מטפס על הקירות, and מקיר לקיר.

We started with the Western Wall, so let's end with כותל המזרח (the Eastern Wall). The original meaning of כותל המזרח – or "Mizrach Vant" in Yiddish – refers to the eastern wall of the synagogue. This wall was given a place of honor because Jews in Europe prayed facing east toward Jerusalem (as Rabbi Yehuda Halevi famously wrote: "לבי במזרח ואנכי בסוף מערב").

Over time, the phrase evolved metaphorically to describe an honored, prestigious seat or status within any group or organization. This association likely comes from the synagogue's eastern wall echoing the eastern wall of the Temple Mount itself, mirroring the idea of a synagogue as a "miniature Temple" (מקדש מעט).
