Rabbis of the Mishnah and Gemara, the Jewish oral law that developed from the second to the sixth century C.E., certainly knew nothing of the term transgender. But the rabbis did recognize variations in sexual anatomy and debated the halachic status of those who fell somewhere between clear-cut male and clear-cut female. Below are the categories the rabbis identified.
