'Two' in the Bible

It happened in the days when the judges judged, that there was a famine in the land. A certain man of Bethlehem Judah went to live in the country of Moab, he, and his wife, and his two sons.

The name of the man was Elimelech, and the name of his wife Naomi, and the name of his two sons Mahlon and Chilion, Ephrathites of Bethlehem Judah. They came into the country of Moab, and continued there.

Elimelech, Naomi's husband, died; and she was left, and her two sons.

Mahlon and Chilion both died, and the woman was bereaved of her two children and of her husband.

She went forth out of the place where she was, and her two daughters-in-law with her; and they went on the way to return to the land of Judah.

Naomi said to her two daughters-in-law, "Go, return each of you to her mother's house: Yahweh deal kindly with you, as you have dealt with the dead, and with me.

So they two went until they came to Bethlehem. It happened, when they were come to Bethlehem, that all the city was moved about them, and [the women] said, "Is this Naomi?"

All the people who were in the gate, and the elders, said, "We are witnesses. May Yahweh make the woman who has come into your house like Rachel and like Leah, which two built the house of Israel; and treat you worthily in Ephrathah, and be famous in Bethlehem.
