Matius 9:11

9:11 When the Pharisees ¹  saw this they said to his disciples, “Why does your teacher eat with tax collectors and sinners?” ² 

[9:11]  ¹ sn See the note on Pharisees in 3:7.

[9:11]  ² sn The issue here is inappropriate associations. Jews were very careful about personal associations and contact as a matter of ritual cleanliness. Their question borders on an accusation that Jesus is ritually unclean.
