ותבער בהם אש, “and the Lord’s fire raged among them;” this was a punishment fitting the crime, as they had dared to look at the glory of the Lord which is also known as fire, i.e. אש אוכלת, Exodus 24,17. They had already been warned not to do this in Exodus chapter 24. Rashi explained this in connection with Exodus 24,10.
Rabbeinu Bahya
באלוני ממרא, “at the terebinths of Mamre.” The Torah informs us of the site where the circumcision took place. This was also the place where he received an immediate sign that G’d appreciated Avraham’s deed.
We find that manifestations of G’d’s presence to the prophets occur by means of 1) fire; 2) wind; 3) water, and 4) earth [either of the four basic raw material the terrestrial earth is made of. Ed.] G’d appeared to Moses in a burning bush (Exodus 3,2). He also appeared to the entire Jewish nation in an environment of fire (Deuteronomy 4,36: “He let you see His great fire, and you heard His words out of the fire”). In Exodus 24,17 G’d’s manifestation is described as “a consuming fire on top of the mountain.”
In connection with the ascent to heaven by the prophet Elijah we read in Kings II 2,1 “when the Lord was about to take Elijah up to heaven in a whirlwind, etc.” In Kings I 19,11 והנה ה' עובר ורוח גדולה וחזק מפרק הרים, ”there was a great and mighty wind; splitting mountains and shattering rocks by the power of the Lord.” We also encounter a manifestation of G’d through a mighty wind in Job 38,1 “Then the Lord replied to Job out of the tempest and said, etc.”
An instance of G’d manifesting Himself by means of water is found in Ezekiel 1,1 “It was in the thirtieth year... when I was in the community of exiles by the river Kevar, etc.” We encounter another example of G’d manifesting Himself by means of water in Ezekiel 1,24 ”I could hear the sound of their wings like the sound of mighty waters, like the sound of Shaddai."
We find G’d manifesting Himself in connection with earth in Ezekiel 43,2 “the whole earth is filled with His glory.” We also find a revelation described as “and the earth was lit up by His Presence.” In this instance, G’d manifested Himself to Avraham by means of a tree. The Midrash uses the word אלוני ממרא to emphasise the fact that these were trees, אילנות. Actually, Mamre was the name of one of Avraham’s close associates as we know from 14,13 “Mamre the Emorite, the brother of Aner and Eshkol who were allies of Avram.” Had the Torah only wanted to tell us that Avraham circumcised himself near the place where Mamre lived, it would have been appropriate to describe the area as ערבות ממרא, “the fields of Mamre.” The emphasis on the word אלוני shows that the Torah wanted to draw our attention to the fact that we are talking about a tree or trees. When Avraham told the men who came to visit to rest “under one of the trees,” this shows that there was more than one tree.
Why did G’d choose a tree to be the site at which He manifested Himself to Avraham on this occasion? It was because the angel was going to tell him that within a year he and Sarah would have a son. He would experience something similar to that which was experienced by an aged tree which still produced fruit. It is written in Job 14,7-9: “There is hope for a tree; if it is cut down it will renew itself; its shoots will not cease. If its shoots are old in the earth, and its stump dies in the ground, at the scent of water it will bud and produce branches like a sapling.” We also have a verse comparing the righteous to trees in Psalms 1,3 “He (the righteous) is like a tree planted beside streams of water which yields its fruit in season.” This is also how Rabbeinu Chananel explains our verse.

Abarbanel
...The Holy One Blessed be He desired to sanctify His Altar and His Tabernacle through the descent of the divine fire there for four reasons: 1) The divine Camp and the collective of his angels is always likened to fire, as it is written, "the appearance of the Presence of the Lord was like a consuming fire" (Exodus 24:17). Ezekiel beheld his prophecy with fire, as it is written, "flashing fire...and in the center of it, in the center of the fire, a gleam as of amber" (Ezekiel 1:4). And Daniel said, "His throne was tongues of flame; its wheels were blazing fire. A river of fire..." (Daniel 7:9-10). Since the divine camp is called 'fire' in the words of the prophets, fire came to the Tabernacle and to the Temple to indicate that the Divine Presence and Glory of the Lord were there with the holy myriads. ... 2) The human intellect doubts the divine Providence due to the exalted nature of the Provider and the lowliness mortal individuals. He, may He be blessed, is non-corporeal and does not have accidents that would allow humans to perceive Him. Therefore, in order to ingrain the truth of his Providence in the minds of His servants, together with His exalted status, God brought fire down from heaven onto the altar... 3) The divine Torah is likened to fire, as it is written, "Lightning [אש] flashing from His right" (Deuteronomy 33:2). The prophet said, "Behold, My word is like fire" (Jeremiah 23:29). Once the Tabernacle was completed and Israel [had brought] their offerings, fire descended from Heaven to express that the true perfection consists in keeping the Torah that is likened to fire, as it was granted from Heaven. 4) Israel were in deep doubt about how the offerings could be of 'pleasant odor' to the Name, since He is distinct from all physicality. Therefore, He needed to bring down fire from Heaven to consume the burnt offering and the fats so that all the people could see with their own eyes that God was pleased with their actions...
