Matthew 5:28
But I say to you, everyone who looks at a woman with an improper sexual desire for her [body], has already been sexually unfaithful to his mate in his heart.
2 Peter 2:14
Their eyes are filled with sexual lust, and they are never satisfied when it comes to sinning. They entice unstable people and have hearts trained to be greedy [i.e., they continually desire the possessions of others]. [In this condition] they are under God's curse.
1 John 2:16
For all that makes up the world, namely, the improper desires of the physical body, the improper desires for what is seen, and the [boastful] pride over life's possessions; these are not from the Father, but from the [godless] world.
