"You heard it said 'don't committ adultery.' But now i tell you whoever looks at a women with a lust has committed adultery with her in his heart."

I wanna ask here how is the historical interpretations of this passage.

Because i am confusing whether it is meant to say, if you look at a girl to be horny than you committ adultery.

However on second thought, maybe the statement said, if you look at a girl WITH THE INTENTION/DESIRE OF COMMITTING ADULTERY (STEALING THAT WHICH ISNT YOURS) then it is adultery.

I ask how did the early church fathers, different denomination, different priests/church fathers/religious leaders interpret this passage throughout world history.

Are there books/essays discussing this. How does other religion like judaism etc. view it.

And what would Jesus have meant exactly here.

Thanks.

Also i am asking it here so that i dont get an answer that is biased to any particular religion/ideology/opinion.
