Luke 6:32 - Ellicott's Commentary On The Whole Bible

For if ye love them which love you. — See Note on Matthew 5:46, and note St. Luke’s use, as writing for Gentiles, of the wider term “sinners,” instead of the more specific “publicans,” which pointed the maxim, perhaps, for those who originally heard it, and certainly for St. Matthew’s Jewish readers. There is also a slight variation in the form of the closing questions — St. Luke’s “what thank have ye” pointing to the expectation of gratitude in return for good offices, St. Matthew’s “what reward” to a more concrete and solid payment.
