Luke 5:30-32

[30] But  their  scribes  and  Pharisees  murmured  against  his  disciples,  saying,  do ye eat  and  drink  with  publicans  and  sinners?  [31] And  Jesus  answering  said  unto  them,  They that are whole  need  not  a physician;  but  they that are  sick.  [32] I came  not  to call  the righteous,  but  sinners  to  repentance.
