I desire mercy and not sacrifice.This quote from Hosea 6:6 is used again in Matthew 12:7. The Pharisees were meticulous about observing the Law and offering sacrifices and tithes over the smallest things (Matt. 23:23), yet their hearts were dark and hard. Those who think they are righteous have no need of a Savior, just as those who are healthy will not seek a physician. Jesus had compassion, both on the sick and the sinful, but could not help the self-righteous.
