'Easy' in the Bible

You are like a wild female donkey brought up in the wilderness. In her lust she sniffs the wind to get the scent of a male. No one can hold her back when she is in heat. None of the males need wear themselves out chasing after her. At mating time she is easy to find.

Lord, you have always been fair whenever I have complained to you. However, I would like to speak with you about the disposition of justice. Why are wicked people successful? Why do all dishonest people have such easy lives?
