The Medrash (Yalkut Shimoni, Remez 24) states: “Avrohom had a daughter and her name was Bakol.”
The Kobriner Rebbe zy”a (Sefer Imros Moshe) explains that the word “bas” (daughter) connotes a “middah’ (as in Yechezkel 48:10: “U’bas tzedek yihiyeh lachem. You shall have a trait of justice). Accordingly, the Medrash can be read as saying that Avrohom had the middah (“bas”) of making do with whatever he had. Even if he only had a little, he accepted this as Hashem’s will and felt as if he lacked nothing, as he understood that it was for his benefit.
We also see from this how the greatness of Avrohom’s middah of emunah. He fully believed in Hashem and accepted that whatever He did was for his benefit, and trusted that Hashem would provide him with whatever he needed.
