Matthew 5:46-47

5:46 For if you love those who love you, what reward do you have? Even the tax collectors do the same, don’t they? 5:47 And if you only greet your brothers, what more do you do? Even the Gentiles do the same, don’t they?

sn The tax collectors would bid to collect taxes for the Roman government and then add a surcharge, which they kept. Since tax collectors worked for Rome, they were viewed as traitors to their own people and were not well liked.
