'Seventh Day' in the Bible

So she wept upon him the seven days, - while their banquet lasted, - and it came to pass, on the seventh day, that he told her, because she urged him, and she told the riddle unto the sons of her people.

And the men of the city said to him, on the seventh day - ere yet the sun went in, What is sweeter than honey? And what is stronger than a lion? And he said to them: If ye had not ploughed with my heifer, Ye had not found out my riddle!
