In the back of the book, Primo-genesis...the story the Bible tells, on page Plate 11, written by Howard B. Rand, we find the following chart (see page 6):
Esau -- Adah (one of his Canaanite wives)
Eliphaz – Timna – (daughter of Seir the Horite)
Duke Amalek – We have the origin of the Amalekites, who were the first to attack Israel when they came out of Egypt in the Exodus.
Thus, the Amalekites were descending from Esau and are now called “Jews.”
From Smith Dictionary:
Agag: Possibly the title of the kings of Amalek, like Pharaoh of Egypt. One king of this name is mentioned in Numbers 24:7, and another in 1 Samuel 15:8, 9, 20, 32. The latter was the king of the Amalekites, whom Saul spared contrary to Jehovah’s well-known will. Exodus 17:14 and Deuteronomy 25:17. For this act of disobedience Samuel was commissioned to declare to Saul his rejection, and he himself sent for Agag and cut him in pieces (B.C. about 1070.) Haman is called the AGAGITE in Esther 3:1, 10; 8:3, 5. The jews consider him a descendant of Agag the Amalekite.
Amalekites: a nomadic tribe of uncertain origin, which occupied the peninsula of Sinai and the wilderness intervening between the southern hill-ranges of Palestine and the border of Egypt. Numbers 13:29; 1 Samuel 15:7; 27:8. Their wealth consisted in flocks and herds. Mention is made of a “town,” 1 Samuel 15:5, but their towns could have been little more than stations or nomadic enclosures. The Amalekites first came in contact with the Israelites at Rephidim, but were signally defeated. Exodus 17:8-16. In union with the Canaanites they again attacked the Israelites on the borders of Palestine, and defeated them near Hormah. Numbers 14:45. Saul undertook an expedition against them. ! Samuel 14:48. Their power was thenceforth broken, and they degenerated into a horde of banditti. Their destruction was completed by David. 1 Samuel 30:1-17.
