'Return' in the Bible

Then Mordecai bade them return answer unto Esther, Think not with thyself that thou shalt escape in the king's house, more than all the Jews.

Then Esther bade them return answer unto Mordecai,

but when the matter came before the king, he commanded by letters that his wicked device, which he had devised against the Jews, should return upon his own head, and that he and his sons should be hanged on the gallows.
