'Drink Wine' in the Bible

Come, let’s get our father to drink wine so that we can sleep with him and preserve our father’s line.”

So they got their father to drink wine that night, and the firstborn came and slept with her father; he did not know when she lay down or when she got up.

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

That night they again got their father to drink wine, and the younger went and slept with him; he did not know when she lay down or when she got up.
