Everyone on earth had the same language and the same words.

וַֽיְהִ֥י כָל־הָאָ֖רֶץ שָׂפָ֣ה אֶחָ֑ת וּדְבָרִ֖ים אֲחָדִֽים׃

The Lord came down to look at the city and tower that man had built, and the Lord said, “If, as one people with one language for all, this is how they have begun to act, then nothing that they may propose to do will be out of their reach. Let us, then, go down and confound their speech there, so that they shall not understand one another’s speech.” Thus the Lord scattered them from there over the face of the whole earth; and they stopped building the city. That is why it was called Babel, because there the Lord confounded the speech of the whole earth; and from there the Lord scattered them over the face of the whole earth.

וַיֹּ֣אמֶר יְהוָ֗ה הֵ֣ן עַ֤ם אֶחָד֙ וְשָׂפָ֤ה אַחַת֙ לְכֻלָּ֔ם וְזֶ֖ה הַחִלָּ֣ם לַעֲשׂ֑וֹת וְעַתָּה֙ לֹֽא־יִבָּצֵ֣ר מֵהֶ֔ם כֹּ֛ל אֲשֶׁ֥ר יָזְמ֖וּ לַֽעֲשֽׂוֹת׃ הָ֚בָה נֵֽרְדָ֔ה וְנָבְלָ֥ה שָׁ֖ם שְׂפָתָ֑ם אֲשֶׁר֙ לֹ֣א יִשְׁמְע֔וּ אִ֖ישׁ שְׂפַ֥ת רֵעֵֽהוּ׃ וַיָּ֨פֶץ יְהוָ֥ה אֹתָ֛ם מִשָּׁ֖ם עַל־פְּנֵ֣י כָל־הָאָ֑רֶץ וַֽיַּחְדְּל֖וּ לִבְנֹ֥ת הָעִֽיר׃ עַל־כֵּ֞ן קָרָ֤א שְׁמָהּ֙ בָּבֶ֔ל כִּי־שָׁ֛ם בָּלַ֥ל יְהוָ֖ה שְׂפַ֣ת כָּל־הָאָ֑רֶץ וּמִשָּׁם֙ הֱפִיצָ֣ם יְהוָ֔ה עַל־פְּנֵ֖י כָּל־הָאָֽרֶץ׃

Moshe turned and went down from the mountain with the two Tablets of the Testimony in his hand. They were tablets written on both sides, the writing was [visible] from either side. The Tablets were the work of God, and the writing was the writing of God, engraved upon the Tablets.

וַיִּ֜פֶן וַיֵּ֤רֶד מֹשֶׁה֙ מִן־הָהָ֔ר וּשְׁנֵ֛י לֻחֹ֥ת הָעֵדֻ֖ת בְּיָד֑וֹ לֻחֹ֗ת כְּתֻבִים֙ מִשְּׁנֵ֣י עֶבְרֵיהֶ֔ם מִזֶּ֥ה וּמִזֶּ֖ה הֵ֥ם כְּתֻבִֽים׃ וְהַ֨לֻּחֹ֔ת מַעֲשֵׂ֥ה אֱלֹהִ֖ים הֵ֑מָּה וְהַמִּכְתָּ֗ב מִכְתַּ֤ב אֱלֹהִים֙ ה֔וּא חָר֖וּת עַל־הַלֻּחֹֽת׃
