 The Book of Esther early became the subject of discussion in the schoolhouses, as may be seen from Megillah 10b et seq., where long aggadic passages are joined to single verses.Esther Rabbah is variously connected with these passages.The author of Esther Rabbah often draws directly upon the Yerushalmi, Bereshit Rabbah, Wayikra Rabbah, Pirke De-Rabbi Eliezer, Targumim, and other ancient sources.
