Then it happened one evening that David arose from his bed and walked on the roof of the king’s house. And from the roof he saw a woman bathing, and the woman was very beautiful to behold. 2 Samuel 11:2

Thus begins a long campaign of sin, deception, lying, and murder. The downhill spiral begins with the breaking of one commandment that leads to breaking more and more.
That commandment – You shall not covet your neighbor’s house; you shall not covet your neighbor’s wife, nor his male servant, nor his female servant, nor his ox, nor his donkey, nor anything that is your neighbor’s. Ex 20:17
The coveting commandment is always broken before you proceed to another.
You covet someone’s life before murder. You covet self-preservation before you lie. You covet property before you steal.
Coveting begins with what you see, what you feel, what you experience, or what you hear.

David saw a beautiful woman bathing and coveted.
David would write in Ps 101:3 – I will set nothing wicked before my eyes.
Of course one could argue that Bathsheba wasn’t wicked and that is true.
Bathsheba isn’t an object of sin and that is true but David took his eyes off God to gaze at the woman and his heart, mind, and body followed.
The sin of coveting leads to coveting more sins.

There is more to the story and it will take a bit more time to study it.
Sufficient for now to say keep your eyes on the Lord and keep your mind on His word.
