Genesis 11:6

הן עם אחד BEHOLD, THEY ARE ONE PEOPLE — They possess all the advantage of being one people and of having one language common to all of them, and this is what they begin to do! החלם is infinitive, like אמרם “their speaking”. עשותם “their doing” (i.e. “they speak”, “they do”) — so here: “they begin to do”) (Genesis Rabbah 38:9). לא יבצר מהם וגו' לעשות This is a question (although the ה which introduces an interrogative sentence is absent): SHALL THEY NOT BE RESTRAINED FROM DOING WHAT THEY IMAGINE TO DO? The word יבצר means “restraining”, as the Targum understands it; a similar instance is, (Psalms 76:13) “He restrains (יבצור) the spirit of princes”.

וַיֹּ֣אמֶר יְהֹוָ֗ה הֵ֣ן עַ֤ם אֶחָד֙ וְשָׂפָ֤ה אַחַת֙ לְכֻלָּ֔ם וְזֶ֖ה הַחִלָּ֣ם לַעֲשׂ֑וֹת וְעַתָּה֙ לֹֽא־יִבָּצֵ֣ר מֵהֶ֔ם כֹּ֛ל אֲשֶׁ֥ר יָזְמ֖וּ לַֽעֲשֽׂוֹת׃

And the Lord said, Behold, the people is one, and they have all one language; and this they begin to do: and now nothing will be withheld from them, which they have schemed to do.
