Here lies (very rough translation of 5 line anagram: )A man who worked for the greater good of his community, To life, to living wages to his workers, Day and night dealt in the Torah and merit of kindness,He distributed his wealth always to the poor and indigent,And she answered his righteousness before the Creator of universe. My husband and my father our Holy Teacher, the Rabbi, Elihu, son of the honorable Mordechai Yitzchak the Righteous of blessed memory, Riever, who died 9 Adar 5686, at the age of 52 years. May his soul be bound up in the bond of eternal life.
