O my mountain in the field - The prophet here addresses the land of Judea, which was a mountainous country, Deuteronomy 3:25; but Jerusalem itself may be meant, which is partly built upon hills which, like itself, are elevated above the rest of the country.
O my mountain in the field - i. e., Jerusalem or Zion, called the Rock of the Plain in Jeremiah 21:13. “The field” is the open unenclosed country, here contrasted with the privileged height of Zion.
Or sin - i. e., because of thy sin.
