Wood denotes burning; we know well the burning of human beings, communities, books and traditions. Leprosy denotes isolation, and we know how frightening it is to suffer in isolation when no-one seems to care.
Jews dare not forget the burning that destroyed so much; if we fail to record the lives and traditions that were burnt, they die a second death. Nor can we allow ourselves to forget the time we were shunned like lepers.
Because others showed little concern, we nearly did not survive: and no-one will survive anywhere unless fellow human beings show concern.
