5 Bible Verses about Firstborn Daughters

The firstborn said to the younger, “Our father is aging, and there is not a man on earth [available] to be intimate with us in the customary way [so that we may have children].

So they gave their father wine that night, and the firstborn went in and lay with her father; and he did not know when she lay down or when she got up [because he was completely intoxicated].

Then the next day, the firstborn said to the younger, “Behold, I lay with my father last night; let us make him drunk with wine tonight also, and then you go in and lie with him, so that we may preserve our family through our father.”

The firstborn gave birth to a son, and named him Moab (from father); he is the father of the Moabites to this day.

Now Saul’s sons were Jonathan, Ishvi, and Malchi-shua. The names of his two daughters were these: the name of the firstborn was Merab, and the name of the younger, Michal.
