Then Sayyidna Musa (علیہ السلام) (Moses) brought the Torah from Mount Tur طور (Sinai) and presented it to the Israelites as the book of Allah, some of them were insolent enough to say that they could not believe it until and unless Allah Himself told them in so many words. With the permission of Allah, Sayyidna Musa (علیہ السلام) replied that even this condition would be fulfilled, if they went with him to Mount Tur طور . The Israelites chose seventy men for this purpose. Arriving there, they heard the words of Allah with their own ears. Now, in their perversity, they invented a new ruse. It was not enough, they said, to hear the speech, for they could not be sure whether it was Allah Himself who had spoken to them or someone else. But they promised that they would be finally convinced if they could see Allah with their own eyes. Since it is beyond the power of a living being to be able to see Allah in the physical world, they had to pay for their impertinence, and were killed by a thunderbolt -- the next verse reports their death.
