Now the sons of Saul were Jonathan, Ishvi, and Malchishua. His two daughters were named Merab (his firstborn) and Michal (his younger daughter).

One day the older daughter said to the younger, “Our father is old, and there is no man in the land to sleep with us, as is the custom over all the earth.

So that night they got their father drunk with wine, and the firstborn went in and slept with her father; he was not aware when she lay down or when she got up.

The next day the older daughter said to the younger, “Look, I slept with my father last night. Let us get him drunk with wine again tonight so you can go in and sleep with him and we can preserve our father’s line.”

The older daughter gave birth to a son and named him Moab. He is the father of the Moabites of today.
