And Abraham married another wife named Cetura:

But of Madian was born Epha, and Opher, and Henoch, and Abida, and Eldaa: all these were the children of Cetura.

And the sons of Cetura, Abraham's concubine, whom she bore: Zamran, Jecsan, Madan, Madian, Jesboc, and Sue. And the sons of Jecsan, Saba, and Dadan. And the sons of Dadan: Assurim, and Latussim, and Laomin.

And the sons of Madian: Epha, and Epher, and Henoch, and Abida, and Eldaa. All these are the sons of Cetura.
