'Seventh' in the Bible

She wept the whole seven days of the feast, and at last, on the seventh day, he explained it to her, because she had nagged him so much. Then she explained it to her people.

On the seventh day, before sunset, the men of the city said to him:What is sweeter than honey?What is stronger than a lion?So he said to them:If you hadn’t plowed with my young cow,you wouldn’t know my riddle now!
