'Lustfully' in the Bible

“I have made a covenant (agreement) with my eyes;How then could I gaze [lustfully] at a virgin?

When she lustfully exposed her nakedness, I was disgusted with her, just as I had been disgusted with her sister.

They come to you in crowds, and they sit in front of you as my people. They hear your words, but do not obey them. For they talk lustfully, and their heart is set on their own advantage.
