וַיֹּ֤אמֶר יְהוָה֙ אֵלַ֔י אִם־יַעֲמֹ֨ד מֹשֶׁ֤ה וּשְׁמוּאֵל֙ לְפָנַ֔י אֵ֥ין נַפְשִׁ֖י אֶל־הָעָ֣ם הַזֶּ֑ה שַׁלַּ֥ח מֵֽעַל־פָּנַ֖י וְיֵצֵֽאוּ׃
永恆者對我說：«即使摩西和撒母耳站在我面前，我的心意也不會轉向這百姓。把他們從我面前趕走，讓他們離去吧！»
Rashi
Moses and Samuel Both were needed to beg mercy for Israel, but first they induced them to repent, and afterwards they prayed on their behalf, but they had no idea of turning away My wrath until they had induced them to repent. Moses said (Exodus 32:27), “Let each man put his sword...” (v. 20) “and he scattered it on the surface of the water, etc.” And afterwards (v. 30), “I will ascend to the Lord, perhaps I will atone.” Samuel in Mizpah (I Samuel 7:4,5) “And the children of Israel removed the Baalim,” and afterwards, “‘Gather all Israel to Mizpah, and I shall pray to the Lord on your behalf (sic).’” But you cannot bring them back to Me, therefore do not pray for them.
