Translation:

153. The people of the Book ask thee to cause a book to descend to them from heaven: indeed they asked Moses for an even greater (miracle) for they said: "Show us Allah in public" but they were dazed for their presumption with thunder and lightning. Yet they worshipped the calf even after clear signs had come to them; even so We forgave them; and gave Moses manifest proofs of authority.

Notes (Tafseer)

657. Cf. ii. 55, for the thunder and lightning which affected those who were presumptuous enough to ask that they should see Allah face to face, and ii. 51, and n. 66, for the worship of the golden calf. The lesson is that it is presumptuous on the part of man to judge of spiritual things in terms of material things, or to ask to see Allah with their material eyes when Allah is above material forms and is independent of time and space.
