'Seventh' in the Bible

However she wept before him seven days while their feast lasted. And on the seventh day he told her because she pressed him so hard. She then told the riddle to the sons of her people.

So the men of the city said to him on the seventh day before the sun went down,“What is sweeter than honey?And what is stronger than a lion?”And he said to them,“If you had not plowed with my heifer,You would not have found out my riddle.”
