Edom, Edomites, Idumea

“Edom” From Boyd’s Bible Dictionary:

(red). Called also Idumea and Mount Seir. Name given to Esau, his country and people (Gen. 32:3-19; 33:1-163And Jacob sent messengers before him to Esau his brother unto the land of Seir, the country of Edom. 4And he commanded them, saying, Thus shall ye speak unto my lord Esau; Thy servant Jacob saith thus, I have sojourned with Laban, and stayed there until now: 5And I have oxen, and asses, flocks, and menservants, and womenservants: and I have sent to tell my lord, that I may find grace in thy sight. 6And the messengers returned to Jacob, saying, We came to thy brother Esau, and also he cometh to meet thee, and four hundred men with him. 7Then Jacob was greatly afraid and distressed: and he divided the people that was with him, and the flocks, and herds, and the camels, into two bands; 8And said, If Esau come to the one company, and smite it, then the other company which is left shall escape. 9And Jacob said, O God of my father Abraham, and God of my father Isaac, the Lord which saidst unto me, Return unto thy country, and to thy kindred, and I will deal well with thee: 10I am not worthy of the least of all the mercies, and of all the truth, which thou hast showed unto thy servant; for with my staff I passed over this Jordan; and now I am become two bands. 11Deliver me, I pray thee, from the hand of my brother, from the hand of Esau: for I fear him, lest he will come and smite me, and the mother with the children. 12And thou saidst, I will surely do thee good, and make thy seed as the sand of the sea, which cannot be numbered for multitude. 13And he lodged there that same night; and took of that which came to his hand a present for Esau his brother; 14Two hundred she goats, and twenty he goats, two hundred ewes, and twenty rams, 15Thirty milch camels with their colts, forty kine, and ten bulls, twenty she asses, and ten foals. 16And he delivered them into the hand of his servants, every drove by themselves; and said unto his servants, Pass over before me, and put a space betwixt drove and drove. 17And he commanded the foremost, saying, When Esau my brother meeteth thee, and asketh thee, saying, Whose art thou? and whither goest thou? and whose are these before thee? 18Then thou shalt say, They be thy servant Jacob's; it is a present sent unto my lord Esau: and, behold, also he is behind us. 19And so commanded he the second, and the third, and all that followed the droves, saying, On this manner shall ye speak unto Esau, when ye find him. (Genesis 32:3‑19)
1And Jacob lifted up his eyes, and looked, and, behold, Esau came, and with him four hundred men. And he divided the children unto Leah, and unto Rachel, and unto the two handmaids. 2And he put the handmaids and their children foremost, and Leah and her children after, and Rachel and Joseph hindermost. 3And he passed over before them, and bowed himself to the ground seven times, until he came near to his brother. 4And Esau ran to meet him, and embraced him, and fell on his neck, and kissed him: and they wept. 5And he lifted up his eyes, and saw the women and the children; and said, Who are those with thee? And he said, The children which God hath graciously given thy servant. 6Then the handmaidens came near, they and their children, and they bowed themselves. 7And Leah also with her children came near, and bowed themselves: and after came Joseph near and Rachel, and they bowed themselves. 8And he said, What meanest thou by all this drove which I met? And he said, These are to find grace in the sight of my lord. 9And Esau said, I have enough, my brother; keep that thou hast unto thyself. 10And Jacob said, Nay, I pray thee, if now I have found grace in thy sight, then receive my present at my hand: for therefore I have seen thy face, as though I had seen the face of God, and thou wast pleased with me. 11Take, I pray thee, my blessing that is brought to thee; because God hath dealt graciously with me, and because I have enough. And he urged him, and he took it. 12And he said, Let us take our journey, and let us go, and I will go before thee. 13And he said unto him, My lord knoweth that the children are tender, and the flocks and herds with young are with me: and if men should overdrive them one day, all the flock will die. 14Let my lord, I pray thee, pass over before his servant: and I will lead on softly, according as the cattle that goeth before me and the children be able to endure, until I come unto my lord unto Seir. 15And Esau said, Let me now leave with thee some of the folk that are with me. And he said, What needeth it? let me find grace in the sight of my lord. 16So Esau returned that day on his way unto Seir. (Genesis 33:1‑16)). It lay to the south of Palestine and Moab.

Concise Bible Dictionary:

Name given to Esau because he craved the red pottage of Jacob, Edom signifying red (Gen. 25:3030And Esau said to Jacob, Feed me, I pray thee, with that same red pottage; for I am faint: therefore was his name called Edom. (Genesis 25:30); Gen. 36:1,8,191Now these are the generations of Esau, who is Edom. (Genesis 36:1)
8Thus dwelt Esau in mount Seir: Esau is Edom. (Genesis 36:8)
19These are the sons of Esau, who is Edom, and these are their dukes. (Genesis 36:19)); but the name is more usually given to his tribe and the territory they possessed. This extended from the land of Moab, southward to the Gulf of Akaba, in length about 100 miles, from about 29° 30' to 31° N, and about 35° 30' E. It is a remarkably mountainous district with lofty peaks and deep glens, but also with very productive plains. It had been called mount Seir (Gen. 36:88Thus dwelt Esau in mount Seir: Esau is Edom. (Genesis 36:8)). Some of the rocks were so precipitous that Amaziah killed 10,000 of the children of Seir (Edomites) by casting them down from the rocks, whereby they were dashed to pieces (2 Chron. 25:1111And Amaziah strengthened himself, and led forth his people, and went to the valley of salt, and smote of the children of Seir ten thousand. (2 Chronicles 25:11)). Bozrah and Sela, or Selah, were its chief cities.
When Israel was approaching the land of Palestine, Moses appealed to Edom to let them pass through their country, but they refused. The Israelites therefore returned south by way of the Red Sea (Gulf of Akaba) in order to compass the land of Edom, and then kept to the east of Edom until they reached the land of Moab (Num. 21:44And they journeyed from mount Hor by the way of the Red sea, to compass the land of Edom: and the soul of the people was much discouraged because of the way. (Numbers 21:4)).
Many prophecies speak of its punishment. When the king of the north in a future day invades Palestine and overthrows countries as far as Egypt, “Edom, and Moab, and the chief of the children of Ammon” will escape, being reserved to be subdued by Israel (Dan. 11:4141He shall enter also into the glorious land, and many countries shall be overthrown: but these shall escape out of his hand, even Edom, and Moab, and the chief of the children of Ammon. (Daniel 11:41); Isa. 11:13-1413The envy also of Ephraim shall depart, and the adversaries of Judah shall be cut off: Ephraim shall not envy Judah, and Judah shall not vex Ephraim. 14But they shall fly upon the shoulders of the Philistines toward the west; they shall spoil them of the east together: they shall lay their hand upon Edom and Moab; and the children of Ammon shall obey them. (Isaiah 11:13‑14); Obad. 18-1918And the house of Jacob shall be a fire, and the house of Joseph a flame, and the house of Esau for stubble, and they shall kindle in them, and devour them; and there shall not be any remaining of the house of Esau; for the Lord hath spoken it. 19And they of the south shall possess the mount of Esau; and they of the plain the Philistines: and they shall possess the fields of Ephraim, and the fields of Samaria: and Benjamin shall possess Gilead. (Obadiah 18‑19)). It is from “Edom” that the Lord Jesus is represented as coming “with dyed garments” because of His having executed judgments (Isa. 63:11Who is this that cometh from Edom, with dyed garments from Bozrah? this that is glorious in his apparel, travelling in the greatness of his strength? I that speak in righteousness, mighty to save. (Isaiah 63:1)). Its destruction will be complete (Obad. 1010For thy violence against thy brother Jacob shame shall cover thee, and thou shalt be cut off for ever. (Obadiah 10)).
During the captivity the Edomites extended their dominion in the West and possessed Hebron; and some 300 years B.C. the Nabatheans took Petra (which is supposed to be the same as Sela), and established themselves in the district. They settled down and engaged in commerce, and formed the kingdom called by Roman writers Arabia Petraea. Under the Maccabees the Edomites in the west were conquered, and Hebron was recovered. After possession by the Romans, under the withering influence of Mahometan rule the district came to ruin.
