“Sarah’s lifetime was one hundred years and twenty years and seven years, the years of the life of Sarah” (Genesis 23:1). “Sarah’s lifetime was one hundred years.” “The Lord knows the days of the faultless; their inheritance will last forever” (Psalms 37:18) – just as they are faultless, so their years are faultless: When twenty years old she was like a seven year old girl regarding beauty, and when a hundred years old she was like a twenty year old regarding sin.1Only from the age of twenty is one held accountable for those sins that are punishable by heavenly action.
Another matter, “the Lord knows the days of the faultless [temimim]” – this refers to Sarah, who was faultless in her actions. Rabbi Yoḥanan said: Like a calf without blemish [temima]. “Their inheritance will last forever,” as it is stated: “Sarah’s lifetime was” – why was it necessary to say: “The years of the life of Sarah” at the end? It is to tell you that the lives of the righteous are beloved before the Omnipresent in this world and in the World to Come.2The words “life of Sarah” are repeated to indicate that she in fact had two lives – one in this world and one in the World to Come.
