Which verse mentions the modesty of women, and what is its number?

Perhaps the questioner is referring to what is mentioned in the story of Moses (peace be upon him) when he watered the flocks for the two daughters of the righteous man, and one of them called him, as stated in the Almighty's saying: "Then one of them came to him, walking with shyness. She said, 'Indeed, my father invites you that he may reward you for having watered for us.'" (Al-Qasas: 25).
