God recalls the youthful passion with which the covenant between God and His people was made. Unfortunately, the people did not appreciate God, and instead of seeking closeness with God, they turned to worship worthless and useless gods. All the nations of the world appreciate theior unique traditions and what makes them special, but the poeple of Judah, who have the most special heritage of all, traded it for nothing. It is a double evil, you didn't appreciate Me, and then you turned elsewhere.
