In our current Torah cycle it's hard to miss the theme of mortality. Sarah dies and needs to be buried. By the end of the Torah reading, Abraham too, will breath his last. While Sarah's death takes us by surprise, we are ready and primed for Abraham's. Throughout these narratives, Abraham's age has been mentioned repeatedly after large milestone events in his story: his departure for Canaan (75), the birth of his first son (86), entering the covenant (99), the birth of his second (100), and then finally his death (175). He begins his new life at 75, and what a life it is: full of surprises, challenges and personal growth.
