The Fifth Shulchan Aruch

A stateside individual wanted to send clothing to her relative in Eretz Yisrael. She knew of someone going to Israel for an extended stay who had extra room in his luggage, so she asked the traveler if he could deliver the package. The traveler readily agreed. The relative in Eretz Yisrael was informed of the package but waited months for its delivery. The relative inquired of the traveler, “Didn’t you come to Israel months ago? Why the long delay?” The response was something similar to: “Where does it say in the Torah you have to be nice?”
Let’s put aside the fact that the Chofetz Chaim in Ahavas Chesed spends pages upon pages proving from many biblical sources that one “has to be nice.” Would the fact that the Torah didn’t mention that one has to be nice be an excuse?
The Gemara says in Nazir (45a): It is written, “The nazir shall shave his head at the entrance of the Tent of Meeting (Ohel Moed).” This means he should shave his head after offering his shelamim in the Ohel Moed. The nazir, though, doesn’t actually shave at the Sanctuary. The beraisa asks: Perhaps the Torah means literally that he should actually shave at the entrance of the Sanctuary? The beraisa answers: That would be degrading.
