Born in 1932, Meir Kahane was a controversial American-Israeli rabbi and activist. In 1968, he founded the Jewish Defense League in New York. With the motto of "Never Again," the stated goal of the organization was to protect Jews from anti-Semitism in all its forms. In 1971, he moved his family to Israel, founding the Kach political party, and he was elected to the Knesset in 1984 (the Kach party was later outlawed in Israel).
In 1990, after concluding a speech in a Manhattan hotel, Kahane was fatally shot by an Egyptian-born terrorist. While strangely acquitted of the murder, El Sayyid Nosair was later convicted in relation to the 1993 World Trade Center bombing.
On Shabbat morning, Cheshvan 18, 5779 (Oct. 27, 2018), Pittsburgh’s peaceful Jewish enclave of Squirrel Hill was shattered by gunshots as a crazed anti-Semite attacked worshippers at the Tree of Life congregation, killing 11. It was the deadliest attack on Jews on American soil. Reeling from the pain, Pittsburghers struggled to make sense of the tragedy that had befallen their city, and people around the world responded with an outpouring of love, support, mitzvahs and faith.
Fighting evil is a very noble job. But it is not your mission in life.
Your job is to bring in more light.
Stay completely out of such battles, arguments, and debates.
Not because you aren't able to win. Not because your heart is too delicate to go to war.
But because every bit of your energy needs to be dedicated exclusively to strengthening the good that you have built, to give your very life for it.
Then, only then, can you succeed.
