Saad • EN-TAFSIR-IBN-ABBAS
﴿ إِنَّ هَٰذَآ أَخِى لَهُۥ تِسْعٌۭ وَتِسْعُونَ نَعْجَةًۭ وَلِىَ نَعْجَةٌۭ وَٰحِدَةٌۭ فَقَالَ أَكْفِلْنِيهَا وَعَزَّنِى فِى ٱلْخِطَابِ ﴾
““Behold, this is my brother: he has ninety-nine ewes, whereas I have [only] one ewe - and yet he said, ‘Make her over to me,’ and forcibly prevailed against me in this [our] dispute.””
(Lo! this my brother hath ninety and nine ewes) meaning 99 wives (while I had one ewe) i.e. one wife; (and he said: Entrust it to me, and he conquered me in speech) this is a similitude which they struck for David in order for him to understand what he did to Uriah.
