Maimonides Quote

The generation of Isaiah did not require the detailed description; his account, "I saw the Lord," &c., sufficed. The generation of the Babylonian exile wanted to learn all the details.... Isaiah was so familiar with it that he did not consider it necessary to communicate it to others as a new thing, especially as it was well known to the intelligent.
