Mishnah/Seder Nashim/Tractate Sotah/Chapter 1/7
Hebrew text 
English Translation 
In the standard that man behaves, you behave that way to him. If she adorned herself for the sin - G-d disgraced her. If she revealed herself for the sin - G-d revealed her. If her thigh went first to sin, and afterwards her stomach - behold the thigh is struck first, and afterwards the stomach. And the rest of her body does not escape.
