The book takes place in the Persian period after many Israelites had returned from the Exile to the land of Palestine to rebuild the temple and set up the sacrificial system. Most Israelite captives, however, chose not to return to their homeland. They should have done so for Isaiah and Jeremiah had urged the yet-to-be-exiled nation to come out of Babylon after 70 years and return to the place where the Lord could bless them under the covenantal promises. Esther and Mordecai had not returned to the land and did not seem interested in complying with the prophetic command to return.
