'Own' in the Bible

for he sent letters into all the king's provinces, into every province according to the writing thereof, and to every people after their language, that every man should bear rule in his own house, and should speak according to the language of his people.

And he brought up Hadassah, that is, Esther, his uncle's daughter: for she had neither father nor mother, and the maiden was fair and beautiful; and when her father and mother were dead, Mordecai took her for his own daughter.

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.
