My brother recently introduced me to some new Halachot (laws) about not giving gifts to gentiles and not complimenting them. What are the pertinent Halachot that I should be aware of, so that I'll have an idea of which situations I need to be careful about or ask a rabbi about?
The Kof-k goes through the sugya nicely and provides examples when it would be muter or assur to show favor.
this is link to the sources(I am not going to summarize it because they did that already) http://www.kof-k.org/articles/040108110431W-28%20Lo%20Sichaneim.pdf
In that pdf, there's a reference to Vayikra 7:3 as the part of the Torah that says it is forbidden to show certain favours to goyim. However, when I go to Vayikra 7:3, it only says "And all of its fat he shall offer from it: the tail and the fat covering the innards,". I can't see anything in Rashi's commentary that would lead to that view either. Is the author trying to reference something else, or have I misunderstood?
