The bulk of God's complaints about the priests related to their indifference and unscriptural behaviour towards the weak, the poor, and the sinners. God often directs us to observe the actions of a good shepherd, who often has a completely different mindset than the priest. All animals are important to the shepherd. He will make real efforts to save every lamb... particularly the sick and the weak. The good shepherd also refuses to accept the loss of a lamb; he will look till he finds it. The role of the priest should be the same as the shepherd.
