4643. Verses 2-5 Esau took his wives (femina) from the daughters of Canaan: Adah the daughter of Elon the Hittite; and Oholibamah the daughter of Anah, the daughter of Zibeon the Hivite; and Basemath, Ishmael's daughter, the sister of Nebaioth. And Adah bore Eliphaz to Esau; and Basemath bore Reuel; and Oholibamah bore Jeush, and Jaalam, and Korah. These were the sons of Esau who were born to him in the land of Canaan.

'Esau took his wives from the daughters of Canaan' means the first joining of Natural good - to the affection for apparent truth. 'Adah the daughter of Elon the Hittite, and Oholibamah the daughter of Anah, the daughter of Zibeon the Hivite' means its essential nature which it received from the Ancient Church. 'And Basemath, Ishmael's daughter, the sister of Nebaioth' means the second joining - to the affection for truth from a Divine stem. 'And Adah bore Eliphaz to Esau, and Basemath bore Reuel' means the first derivatives. 'And Oholibamah bore Jeush, and Jaalam, and Korah' means the second derivative. 'These were the sons of Esau who were born to him in the land of Canaan' means from the good of the Lord's kingdom.

352. 'The firstborn of the flock' means the holy which is the Lord's alone. This becomes clear from the firstborn in the representative Church, where everything was holy because it had regard to the Lord, who alone is 'the Firstborn'. Love and faith deriving from it are the firstborn. All love is the Lord's and not a trace of it man's, and this is why the Lord alone is 'the Firstborn'. This was represented in the Churches of the ancient era by the requirement to consecrate the firstborn of man and of beast to Jehovah, Exodus 13:2, 12, 15. It was also represented by the tribe of Levi, which in the internal sense means love - though Levi was born later than Reuben and Simeon, who in the internal sense mean faith - being taken instead of all the firstborn and becoming the priesthood, Numbers 3:40-46; 8:14-20. That the Lord as regards His Human Essence is the Firstborn of all is clear from the following statement in David,

He will cry to Me, You are My Father, My God, and the Rock of My Salvation; I will also make Him as the Firstborn, supreme over the kings of the earth. Psalms 89:26-27.

And in John,

Jesus Christ, the Firstborn from the dead, and Prince of the kings of the earth. Revelation 1:5.

Please note that the firstborn of worship mean the Lord, while the firstborn of the Church mean faith.
