Milkah מִלְכָּ֔ה in the Bible means “counsel.”
The first Milkah was the wife of Nahor, Abraham’s brother. See Genesis 11:29 and 22:20.
She was the grandmother of beautiful Rebekah who married Isaac, the long-awaited promised son of Abraham.
The next Milkah was the daughter of Zelophehad.
She and her four sisters won the right for daughters to inherit their father’s land.
See Numbers 26:33 and 27:11.
