You make some strange statements, ATSOG, and I believe you have missed some major points.
This dreadful accusation is mistaken on 2 counts at least.:
It's not like the murder Esau contemplated is a cold calculated thing, for that's not the kind of boy Esau was.
Esau was not a boy, at the time this took place. I worked it out some time ago, and found that Jacob was about 75 years old at the time, which, if correct, makes Esau also about 75 years of age.
This was a case of pre-calculated usury and coveting, on Jacob's part, leading to purchase, then theft and anger.
You've missed the real reasons for Jacob wanting the birthright.
The birthright carried with it several major rights:
1 The firstborn would receive a double portion of the father's goods when he died
2 If it was a royal family, as today, the firstborn would become the king at the appointed time.
3 The most important for this discussion of Jacob's motives, is the fact that the firstborn had the right to be the priest of the family, and to lead their worship. Hence:
Nu 3:45 Take the Levites
instead of all the firstborn among the children of Israel, and the cattle of the Levites instead of their cattle; and the Levites shall be mine: I am the LORD.
So up to this point in time, the firstborn sons were performing the Levitical roles: everything to do with the family's worship.
By rights, Esau had this privilege, because he had been born first. But did he do so? We have several hints that he didn't.
1 He was a 'cunning hunter, a man of the field' is the description in Gen 25. Which tells us what?
That he was never at home on the sabbath day to lead the worship. He was too busy crawling through the bushes, and fornicating in the idol worshipping brothels (also called 'high places') of the land. Please re-read my remarks on his 'eating and drinking, rising up and going his way' in a previous post.
2 His priestly garments were with Rebekah in the house:
Ge 27:15 And Rebekah took
goodly raiment (= the priestly raiment) of her eldest son Esau, which were
with her in the house, and put them upon Jacob her younger son:
SHE had them. Now we know that there wasn't much love lost between Rebekah and Esau: so for the priestly garments to be WITH HER, tells us that Esau didn't wear them at all.
If Esau wasn't there to perform his priestly duties, then who did them? Jacob, of course.
And this had gone on for many years - it was no new thing.
Esau, says Hebrews 12, was a PROFANE person. What does that mean? Leviticus 21 tells us:
4 But he shall not defile himself, being a chief man among his people, to profane himself.
5 They shall not make baldness upon their head, neither shall they shave off the corner of their beard, nor make any cuttings in their flesh.
This is what Esau did.
And in addition to that, there is this commandment:
7 They shall not take a wife that is a whore, or profane; neither shall they take a woman put away from her husband: for he is holy unto his God.
28.8 And Esau seeing that the daughters of Canaan pleased not Isaac his father;
Ge 36:2 Esau took his wives of the daughters of Canaan; Adah the daughter of Elon the Hittite, and Aholibamah the daughter of Anah the daughter of Zibeon the Hivite;
Aholibamah means 'tent of a high place', and we can guess why she was called that.
The 'daughters of Canaan' were of the sort described above.
We see then, evidence of gross dereliction of priestly duties by Esau. Contempt is a useful word here, and in Mal 1, we have at least 6 connections with this sorry tale of Esau's dereliction. Here are a couple:
6 ¶ A son honoureth his father, and a servant his master: if then I be a father, where is mine honour? and if I be a master, where is my fear? saith the LORD of hosts unto you,
O priests, that despise my name. And ye say, Wherein have we despised thy name?
7 Ye offer polluted bread upon mine altar; and ye say, Wherein have we polluted thee? In that ye say, The table of the LORD is
contemptible.
All this, you remember is in the context of Mal 1.2,3:
2 I have loved you, saith the LORD. Yet ye say, Wherein hast thou loved us? Was not Esau Jacob’s brother? saith the LORD: yet I loved Jacob,
3
And I hated Esau, and laid his mountains and his heritage waste for the dragons of the wilderness.
Esau brought the name of the LORD into gross contempt.
Jacob wanted the priesthood, and wanted it badly, and he waited his chance to buy it from Esau.
Such is Esau's contempt for the priesthood, that for one morsel of meat he sold it. And God is infuriated by his action:
"Thus Esau despised his birthright." Gen 25. 34.
That word 'despised' is an extremely strong word, and is used by Nathan the prophet when he says to David:
2Sa 12:9 Wherefore hast thou
despised the commandment of the LORD, to do evil in his sight? thou hast killed Uriah the Hittite with the sword, and hast taken his wife to be thy wife, and hast slain him with the sword of the children of Ammon.
It is an extremely sorry picture, and these facts cast an entirely different, honourable and favourable light on Jacob's motives. He wanted to serve God, to be His priest officially, and took his opportunity to become the official priest of the family when it came his way.
'Covet earnestly the best gifts' says Paul, and Jacob did.
Esau was under no compulsion to sell it. And this business of his being at the point of death because of hunger is pure nonsense. He could cook, and so well that when Isaac ate Rebekah's cooking, he could not differentiate her cooking from Esau's!
No, he despised it, and in saying what he did:
32 ...Behold, I am at the point to die: and what profit shall this birthright do to me?
he unwittingly furnishes the origin of the Lord's statement:
Mr 8:36 For what shall it profit a man, if he shall gain the whole world, and lose his own life?
