Genesis 36:12

And Eliphaz, the son of Esau, had connection with a woman named Timna, who gave birth to Amalek: all these were the children of Esau's wife Adah.

Then Amalek came and made war on Israel in Rephidim.

Keep in mind what Amalek did to you on your way from Egypt;

Then they came back to En-mishpat (which is Kadesh), making waste all the country of the Amalekites and of the Amorites living in Hazazon-tamar.

The children of Lotan were Hori and Hemam; Lotan's sister was Timna.

Edom will be his heritage, and he will put an end to the last of the people of Seir.

But have no hate for an Edomite, because he is your brother, or for an Egyptian, for you were living in his land.

The Lord of armies says, I will give punishment to Amalek for what he did to Israel, fighting against him on the way when Israel came out of Egypt.

The sons of Eliphaz: Teman and Omar, Zephi and Gatam, Kenaz and Timna and Amalek.
