At gayundin, ang Lakas ng Israel ay hindi magsisinungaling at hindi magbabago ng Kanyang pasya; sapagkat hindi Siya tao upang magbago ng pasya.”

“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.

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.
