Sforno on Genesis 28:12/ספורנו על בראשית כ״ח:י״ב

1והנה מלאכי אלוקים עולים ויורדים..והנה ה' נצב עליו, this foreshadowed the future when the “angels of G’d” the superpowers who had become very powerful in our world would begin their decline and end up at the bottom of the rungs of the ladder. The Lord G’d Who stood above the ladder is the symbol of the promise that G’d will never abandon the Jewish people, as we know from Jeremiah 46,28 כי אעשה כלה בכל הגויים ואותך לא אעשה כלה, “even when I utterly destroy all the gentile nations, I will not destroy you.”
