Genesis 11:3

איש אל רעהו ONE TO ANOTHER — One nation to the other: Mizraim to Cush, Cush to Put. and Put to Canaan (Genesis Rabbah 38:6). הבה means, “Prepare yourselves”. Wherever the word הבה (come) occurs it has the meaning of “prepare”, meaning that they should get themselves ready and unite for some work or plan or burden (undertaking). “Come, get ready”: in old French appareiller; English to prepare. לבנים BRICKS — For there is no stone in Babel which is a plain. ונשרפה לשרפה AND BURN THEM THOROUGHLY — This is how bricks, which in old French are called Tuiles, English tiles, are made: they fire them in a furnace. לחמר FOR MORTAR to plaster the walls.

וַיֹּאמְר֞וּ אִ֣ישׁ אֶל־רֵעֵ֗הוּ הָ֚בָה נִלְבְּנָ֣ה לְבֵנִ֔ים וְנִשְׂרְפָ֖ה לִשְׂרֵפָ֑ה וַתְּהִ֨י לָהֶ֤ם הַלְּבֵנָה֙ לְאָ֔בֶן וְהַ֣חֵמָ֔ר הָיָ֥ה לָהֶ֖ם לַחֹֽמֶר׃

And they said to one another, Come, let us make bricks, and burn them thoroughly. And they had brick for stone, and slime had they for mortar.
