“Abraham came to lament for Sarah, and to weep for her” – from where did he come? Rabbi Levi said: He came from Teraḥ’s burial to [that of] Sarah. Rabbi Yosei said to him: But is it not so that Teraḥ’s burial preceded Sarah’s burial by two years?14Teraḥ died when Abraham was one hundred thirty-five years old (see Genesis 11:26 and 11:32), and Sarah died when he was one hundred thirty-seven years old (see Genesis 17:17). Rather, from where did he come? From Mount Moriah.15Where the binding of Isaac had taken place. Sarah died as a result of grief over that incident. That is why the binding [of Isaac] is juxtaposed to “Sarah’s lifetime was.”
