וְגַם֙ נֵ֣צַח יִשְׂרָאֵ֔ל לֹ֥א יְשַׁקֵּ֖ר וְלֹ֣א יִנָּחֵ֑ם כִּ֣י לֹ֥א אָדָ֛ם ה֖וּא לְהִנָּחֵֽם׃
А также Слава Израиля не будет ни лгать, ни раскаиваться; ибо Он не человек, что должен покаяться.'
Tze'enah Ure'enah
“Moreover, the Glory of Israel does not deceive” [15:29]. Samuel said: Though your kingship will be ended, but Israel will remain eternal and the Holy One will preserve the good that Israel has been promised.10Rashi, I Samuel, 15:29.
Rashi
But, the Eternal One of Yisroel neither lies. And if you will say, 'I will repent of my sin before Him,' it will no longer avail to take the kingship from the one to whom it was given, for the Holy One, Blessed is He, Who is the Eternal One of Yisroel, will not lie by not giving the good to whom He said to give it.
