“And Isaac brought her [Rebecca] into his mother Sarah’s tent, and took Rebeccah, and she became his wife; and he loved her. And Isaac was comforted for his mother (Bereishith 24:67).”
The great medieval Bible commentator, Rabbi David Kimhi (known popularly as Radak), noted: “Although three years had passed between Sarah’s death and Isaac’s marriage to Rebeccah, yet he was mourning her [Sarah], and was comforted in that [Rebeccah] was good as his mother was.”
It appears, then, that Isaac mourned his mother inconsolably for three years. But once Rebeccah entered his life, “he was comforted for his mother.” Rebeccah had those qualities and virtues which characterized Sarah, and Isaac finally found consolation from the loss of his mother.
What is consolation?
