'Seventh Day' in the Bible

So she kept on crying in front of him for the entire seven days of the wedding party. On the seventh day he told the solution to her because she nagged him, and then she told the solution to the riddle to her relatives.

Then the men of the city answered him just before sunset on the seventh day: "What is sweeter than honey? What are stronger than lions?" Samson responded, "If you hadn't plowed with my heifer, you wouldn't have solved my riddle."
