Three Torah Libraries
“What is striking about Judaism as a whole is that the Torah is not the sum total of kitvei kodesh, sacred Scripture. It is merely the first and holiest of what are essentially three libraries, the others being Nevi’im and Ketuvim, the Prophets and the Writings. One way of summarising the difference between them is this: The Torah is God’s word to human beings. Nevi’im represents God’s word through human beings. Ketuvim are the words of human beings inspired by ruach hakodesh, the “holy spirit,” to God.”
