"Yet you say, 'The Lord's conduct is unjust!' Hear, O house of Israel: Is my conduct unjust? Is it not your conduct that is unjust?

“Now look, I clap My hands together against the dishonest profit you have made and against the blood shed among you.

“Her officials within her are like wolves tearing their prey, shedding blood, and destroying lives in order to make profit dishonestly.

So My people come to you in crowds, sit in front of you, and hear your words, but they don’t obey them. Although they express love with their mouths, their hearts pursue dishonest profit.
