Kommentar zu Dewarim 32:39

ראו עתה SEE NOW — Realise now from the punishment which I have brought upon you and from which there was no one to save you, and, on the other hand, from the help which I will render you and there will be none who can prevent Me,

For it is I! I am the One!. It repeats the word “I” to negate the view of those who say that there are two deities, one who rules over good, and one who rules over evil… The proof of this is that it states, “I put to death and make live … and no one can rescue from My grasp.” If there was another deity with Me, he would save from My hand, and the dead would live, the living would die instantly. From this you can understand and know that there is no other deity Our Sages learned from here the source for the resurrection of the dead in the Torah (Pesachim 68a), as it states, “I put to death and make live.” One might think that this refers to putting one person to death and making another person live, therefore the verse states, “I smite and I will heal.” Just as smiting and healing are referring to the same person , so too death and life refer to the same person. The support for their opinion is that it first states, “put to death” and then “make live”.

ראו עתה כי אני אני הוא, realise now that it had been I Who had brought disaster in exile upon you!
