The Yerushalmi, corroborated by Tanhuma, says that the tablets were two large sapphire stones, and weighed too much to be possibly carried by one person. The letters God engraved on them miraculously lightened them. This allowed Moses to carry the tablets. When the letters “saw” the Golden Calf which the Jewish people had made, they were revolted and “flew” out of the tablets, back to their divine source, leaving Moses with a burden he could not bear. So Moses dropped them. [Taanit Y 4:5; also Tanhuma on Ki Tisa 30]
But practically all other commentators say Moses willfully smashed the tablets. This is corroborated by the plain text of the Torah:
So I gripped the two tablets, flung them away with both my hands, and smashed them before your eyes. [Deut. 9:17]
Did anybody try to resolve the contradiction?
