Comentário sobre Gênesis 27:44

אחדים means A FEW.

עד אשר תשוב חמת אחיך. "until such time as your brother's anger subsides." Anger has a habit of cooling with the passage of time. The reason that Rebeccah continued to belabour the same point in verse 45 was that she knew that the mere passage of time would not be enough to bring about the desired cooling off of Esau's anger. Until such time as Esau would not become furious when others mentioned what had happened there was no knowing if it would be safe for Jacob to return home.

וישבת...אחדים, a few; since the number אחד is the lowest of the numbers it is no more than natural to describe a small number in terms of a multiple of “one.”
