הוא אדום, who is identical with Edom, etc. This statement is repeated three times in this paragraph. Seeing that G'd has sworn to destroy Edom the Torah had to tell us that Esau is identical with Edom. The Torah also mentioned the town where Esau lived in verse 8; according to Talmudic practice when a statement is not needed in the context in which it is written it may be applied to another context; in this instance the Torah means the town Esau lived in. In verse 19 the Torah also mentions the sons of Esau once more, identifying them with Edom to tell us that all of Esau's descendants will go up in flames at the time when the prophet's assurance (Ovadiah 18) that "Israel will become a flame and Esau the straw to be consumed" will materialise. The reason they are all included is that the Torah has described them all as Edom. All of this is hinted at in Jerusalem Talmud Nedarim 3,5 which describes that in the future Esau will wrap himself in a Talit and occupy a seat amongst the righteous. G'd, however, will remove him from there. Please read what I have written in this connection on verse 31.
Radak
והיה ברכה, the construction והיה is similar to the future tense (not imperative) תהיה, i.e. “you will become.” [the author, presumably, finds it difficult for man to be commanded to be a source of blessing. How does one go about carrying out such a directive? Ed.] We encounter a similar construction as an imperative when G’d orders Moses to ascend the mountain and to die there on the mountain, עלה ומות בהר, seeing that “dying” is understood to be something passive, not active. Hence he would translate that verse also as “ascend the mountain where you will die.” (Deuteronomy, 32,48-50) Similar constructions which describe something impossible are found in Ovadiah 1,4 ואם בין כוכבים שים קנך, where one cannot order someone to make his nest among the stars. These formulations are substitutes for regular future tenses. G’d is telling Avram that his blessings and his fame will be so great that they will spill over to benefit those around him. This promise has become fulfilled to such an extent that when people bless their children they wish them: “may the Lord bless you with the blessing of Avraham”

A Midrashic approach (Tanchuma Tzav 2) to the words היא העולה, “it is the burnt-offering.” The reference is to the Roman Empire which is the most arrogant Empire, constantly aggrandizing itself. The same Midrash also states that anyone who aggrandizes himself will eventually be judged by fire. They base this on what happened to the generation of the deluge who had boasted of their own importance saying: (Job 21,15) “who is Shaddai that we should serve Him?” They were judged by fire as it is written (Job 6,17) ”when they thaw they vanish; in the heat they disappear where they are.” The people of Sodom were judged by fire because they were too proud, as we know from Ezekiel 16,49: “Only this was the sin of your sister Sodom: ‘arrogance!’ She and her daughters had plenty of bread and untroubled tranquillity; “ they were judged by fire as we know from Genesis 19,24: “G’d caused it to rain on Sodom and Gomorrah sulfur and fire.” Pharaoh was also judged by fire seeing he was so arrogant and had said: “who is Hashem that I should listen to Him?” (Exodus 5,2). He had also claimed: “the river Nile belongs to me and I have created it!” (Ezekiel 29,3). We know that he was judged by fire from Psalms 18,14: “Then the Lord thundered from heaven, the Most High gave forth His voice, hail and fiery coals.” We have also been told in Exodus 9,24: ”there was hail which contained fire within it.” Another arrogant king who was punished by fire was Sancheriv who had boasted (Kings II 19,23) “it is I who have climbed the highest mountains, to the remotest parts of Lebanon, and have cut down its tallest cedars, its choicest cypresses.” He was judged by fire as we know from Isaiah 10,16 ”and under its body (כבודו) shall burn a burning like that of fire, destroying frame and flesh.” Something similar happened to boastful Nebuchadnezzar who had been arrogant enough to proclaim (Isaiah 14,14): I will mount the back of a cloud- I will match the Most High.” He had also said (verse 13): “I will climb to the sky higher than the stars of G’d.” Furthermore, he had said: (Ovadiah 4) that he would ascend beyond the stars. As a result of such boastful statements by their king, his soldiers were burned by fire.
When you check Daniel 3,3 where the preparations for the inauguration of Nebuchadnezzar’s giant golden image are described, mention is made of eight nations, i.e. you will find the names: Adragozariah and seven others. When mention is made of the celebration a second time, i.e. in verse 27, we find that 4 of these nations are no longer mentioned. The Talmud Sanhedrin 92 suggests that the other four nations (i.e. their honour guards representing them at Nebuchadnezzar’s court) had been burned to death. According to Rashi it was the same fire which consumed the men heating the kiln into which Chananyah, Mishael and Azaryah were to be thrown.” Thus far the Midrash [approximately. Ed.]
