What did Bil'am mean to when he said "Lo Ish Keil Viyechazev"?
Rashi: 'Hashem swore to bring them to the land of the seven Cana'ani nations and to inherit it, and you think to kill them in the desert'?!
Rashbam: He is not a person, to retract so soon from the B'rachah that He conferred upon Yisrael earlier in the day, 1 bearing in mind that Yisrael had not sinned in the interim.
Targum Yonasan: 'Not like the promises of man are the promises of the Living G-d, Master of the World
See Pasuk 10.
What was he referring to when he said "u'Ven Adam Veyisnecham"?
Refer to Sh'mos 32:14:151:1.
Rashbam: Is He a human-being, that He should regret?
Targum Yonasan: 'Nor are His deeds like those of a human-being who changes his mind'.
To whom does "ha'Hu Amar ve'Lo Ya'aseh ... " pertain?
Rashi #1: With reference to Hashem (the subject of the Pasuk), in the form of a rhetorical question, it means 'Would He say and not do, speak and not carry out?'
Rashi #2 (citing Targum Onkelos): With reference to 'Ish' (mentioned together with the subject) 'He says and does not do, promises and does not carry out. But Hashem says and does, promises and carries out!'
Da'as Zekenim citing Bechor Shor: It applies to Hashem, for matters that depend on man's actions. He does say [to punish] and not do, if man repented, 1 or say to reward [and not do] if man sours, like it says in Yirmeyah 18:7-10. All know that from the beginning, Hashem said with intent to retract if they change their deeds. 2
Targum Yonasan: 'He (the human-being) retracts from his decrees, but the Master of the World promised to multiply this nation like the stars of the heaven and to make them inherit the land of the Cana'anim. Is it possible that what He said He will not do? Is it possible that what He promised He will not carry out?!'
Chomas Anach (Yirmeyah 18): Perhaps Teshuvah is only for Yisrael, but even for Nochrim, it helps to delay punishment, like in Ninveh, Or, part of the Gezeirah is canceled
Alshich (Yirmeyah 18): We have a tradition that Hashem never retracts from a promise for good! That is if they listen to Hashem, just stumble in Aveiros. If they do not even want to listen, He retracts. Radak says that the Navi means that Hashem did good, and later reversed it, This is wrong.
Here it says "Lo Ish Kel vi'Chazev u'Ven Adam v'Yisnecham", and it says "va'Yinachem Hashem", "Nichamti Ki Asisi ha'Adam", "Nichamti Ki Himlachti Es Sha'ul" (Bereishis 6:6,7), Shemos (32:14), Shmuel (1:15:10)!
Refer to Shemos 32:14:151:1 and the note there.
Moshav Zekenim: It was Nechamah (consolation) for Hashem that He made man from earth, to which he will return, and not from fire. It was Nechamah that He anointed Sha'ul, a Tzadik, with whom Hashem is exacting (to kill him for a small matter, and David's reign can begin now), and not a Rasha, for whom Hashem waits until his measure is full. 1
Da'as Zekenim citing Bechor Shor: "Nichamti Ki Asisi"
