Abraham dan Sara sudah tua dan lanjut usianya, dan Sara sudah tidak lagi mengalami haid seperti yang biasa dialami perempuan.
Ramban
‘BA’IM BAYAMIM’ (ADVANCED IN DAYS). In his youthful days a man is called “standing in days,” and they are referred to as “his days” because they belong to him, just as in verse The number of thy days will I fulfill.97Exodus 23:26. But when he gets old and has lived longer than most people of his generation, it is said of him that he is ba bayamim, [literally, “came into days”], because it is as if he came into another land, travelling from and arriving in a city each and every day.
