 The author has collected these teachings from the Mishnah, Tosefta, Mekhilta, Sifre, Yerushalmi, Bereshit Rabbah, Leviticus Rabbah, Shir ha-Shirim Rabbah, Kohelet Rabbah, Eichah Rabbah, Ruth Rabbah, Midrash Esther, Midrash Tehillim, Pesikta de-Rav Kahana, Pesikta Rabbati, and Tanhuma.Only once does he quote a teaching from Talmud Bavli (Eruvin 64a), which he introduces with the words "Taman amrin" (They say there).This, as well as the fact that all the amoraim mentioned in this midrash lived in the Land of Israel, justifies the assumption that its compiler lived there as well.
