Another interpretation: "and behold, angels of God" - this is Daniel. "Ascending and descending on it" - for he ascended and brought up what had swallowed him out of its mouth. "And behold, the LORD stood over him" - "Daniel, servant of the living God" (Daniel 6:21).

Yalkut Shimoni on Torah 119:6
דָּבָר אַחֵר, וְהִנֵה מַלְאַכֵי אֱלֹהִים, זֶה דָּנִיּאֵל. עֹלִים וְיֹרְדִים בּוֹ, שֶׁעָלָה וְהוֹצִיא בִּלְעוֹ מִתּוֹךְ פִּיו וְהִנֵה ה' נִצָּב עָלָיו, "דָּנִיֵּאל עֲבֵד (דְּ)אֱלָהָא חַיָּא".
