'Own' in the Bible

Hear, O our God; for we are despised: and turn their reproach upon their own head, and give them for a prey in the land of captivity:

Then I sent unto him, saying, There are no such things done as thou sayest, but thou feignest them out of thine own heart.

And it came to pass, that when all our enemies heard thereof, and all the heathen that were about us saw these things, they were much cast down in their own eyes: for they perceived that this work was wrought of our God.
