Moshe Rabbenu, in Shemot 33,16 says וְנִפְלִ֙ינוּ֙ אֲנִ֣י וְעַמְּךָ֔ We ( the Jewish people) should be separated from the rest of the world. And right after that, God introduces the 13 Attributes of Mercy, which is a special covenant called the Covenant of the 13 Attributes that is made specifically for the Jewish people. This is what bothered the Greeks. They were bothered by anything that made the Jewish people stand out, apart from the rest of the world. These 13 attributes are what separate us. The way we describe our keeping the 13 attributes of mercy is to ‘ Go in the ways of God .’ Just like He is Rachum , we have to be be Rachum, just like He is Hanun we have to be Hanun . We must act in those ways, but why? Because of the rule that a son emulates his father. The Jewish people are called children of God, and therefore we are the ones that emulate God. We are the ones that live up to the Tzelem Elokim / image of God. The Tomar Devorah tells us that this why we have to live up to and emulate those 13 traits of God. With this, the sefer Yerach L’Moadim, from Rabbi Yerucham Olshin, the Rosh Yeshiva of Lakewood explains a custom brought down by the Magen Avraham, on Shuchan Aruch, brought down by the Mishna Berura and the Kaf HaChaim, that it's customary for young, poor children to go collect money on Hanukah. That's really where the famous Hanukah gelt comes from. Some people want to say it's a Gentile custom, but it's not. It was really for the poor. The custom might have been to just give it as gifts, but there was a concept of giving money to children. Of course, they didn't want to differentiate wealthy and poor when giving money to children. And what's the reason? It’s based on Rambam in Hilchot Matanot Ani’im , chapter 10, Halacha 2, which says, all Jewish people are like brothers, like it says, you are children of God. If we're children of God, we're all brothers. And if a brother doesn't have mercy on his brother, who will have mercy on him? And who are the poor of the Jewish people looking up to? To their Jewish brethren, that are going to help them. Therefore, the Rambam says that the Mitzvah of Sedaka clearly comes from the concept of being children of God, and therefore being brothers to each other. And if the point that the Greeks were trying to obliterate was the fact that we are children of God (and therefore brothers to each other), we must go out of our way and strengthen ourselves in the trait of being brothers and children of Hashem, by specifically giving Sedaka during the holiday of Kislev. That's an important Ahavat Yisrael connection to the holiday of Hanukah. Have a wonderful day.
