Take the Torah, Or Else... (Jethro)

Jews did not have much choice when offered the Torah. God told them that if they did not accept it, He would destroy the world and turn it back to void. 

To make the offer actionable, God formulated it as such: "And it was on the third day" (בהית הבקר ויהי). The first letters of these three words spell bohu (בהו) - which implies destruction.

(Incidentally, other nations were also offered the Torah but refused it as not fitting their nature.)
