'Own' in the Bible

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

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

but when this became known to the king, he commanded by letters that his wicked device, which he had devised against the Jews, should return on his own head, and that he and his sons should be hanged on the gallows.
