The word(s) "ewes" appears 2 time(s) in 2 verse(s) in Quran in Saheeh International translation.

(1) Indeed this, my brother, has ninety-nine ewes, and I have one ewe; so he said, 'Entrust her to me,' and he overpowered me in speech."

(2) [David] said, "He has certainly wronged you in demanding your ewe [in addition] to his ewes. And indeed, many associates oppress one another, except for those who believe and do righteous deeds - and few are they." And David became certain that We had tried him, and he asked forgiveness of his Lord and fell down bowing [in prostration] and turned in repentance [to Allah].
