Commento su Genesi 22:8

יראה לו השה — this means as much as: He will look out for and choose a lamb for Himself, and if there will be no lamb for a burnt offering, then, בני MY SON will be the offering. Although Isaac then understood that he was travelling on to be slain, yet.

ויאמר...אלוקים יראה לו השה לעולה בני, Avraham’s reply to his son is capable of two interpretations. One interpretation would be that the word בני is a response to Yitzchok’s cry or question, meaning “I am here my son; G’d will select the lamb for the burnt offering.” In other words: “don’t worry G’d already knows who is going to be the lamb for the offering. He will put it at our disposal.” The second interpretation of Avraham’s answer would arrange the words as follows: “G’d will select the lamb for the offering; who is the lamb? It is my son.” Yitzchok understood from this that he had been chosen to be the offering. This is why the Torah continues, significantly:

God will see to the lamb for Him (lo): This, "for Him," is superfluous. However no sacrifice can be given in the name of God (Elohim), but rather only in the name of the Lord, as it is found at the end of Menachot. And [the reason] that it is written with the name of God in this section is because the daily burnt-offerings were fixed through this deed, as I wrote on the proximate verse (Haamek Davar on Genesis 22:9). And this is the nature of sustenance in the Land of Israel from when nature was created, as I wrote above 15:7 (Haamek Davar on Genesis 15:7). For this reason the statement was with the name, God (which relates to nature) - as I have written several times. But the essence of the deed is for the name, Lord. And this is the understanding of, "God will see to the lamb for Him" - for the Lord.
