Ishmael, thirteen (baraita at the beginning of Sifra; this collection is largely an amplification of that of Hillel).Eliezer b. Jose ha-Gelili listed 32, largely used for the exegesis of narrative elements of Torah.All the hermeneutic rules scattered through the Talmudim and Midrashim have been collected by Malbim in "Ayyelet ha-Shachar", the introduction to his commentary on the Sifra.
