'Own' in the Bible

“For the [judgment] day of the Lord draws near on all the nations.As you have done, it shall be done to you [in retribution];Your [evil] dealings will return on your own head.

“But on Mount Zion [in Jerusalem] there shall be [deliverance for] those who escape,And it shall be holy [no pagan will defile it];And the house of Jacob shall possess their [former] possessions.
