Matthew 9:11-13

11 The Pharisees noticed this, and they inquired of His disciples, "Why does your Teacher eat with the tax-gatherers and notorious sinners?"

12 He heard the question and replied, "It is not men in good health who require a doctor, but the sick.

13 But go and learn what this means, `It is mercy that I desire, not sacrifice'; for I did not come to appeal to the righteous, but to sinners."
