2 Wives, Milcah and Reumah

"And it came to pass after these things, that it was told Abraham, saying, Behold, Milcah, she hath also born children unto thy brother Nahor? these eight Milcah did bear to Nahor, Abraham's brother. And his concubine, whose name was Reumah, she bare also Tebah, and Gaham, and Thahash, and Maachah." Genesis 22:20-24
