Did David try to sleep with goliaths wife?

No David was a righteous man he did give into fornication and adultery on one occasion with the wife of Uriah Bathsheba but besides that one occasion David was not given to fornication and adultery. Especially with the Enemy that he was set on killing.

Nope. No such thing was mentioned, and David was pretty young when he killed Goliath.

He did sleep with Uriah's wife, very dishonorably, with very bad results.

You should never question what "someone" says.

It was never mentioned in the bible that Goliath had a wife. Or kids.

Next time don't believe what 'someone' says.

Yes, he knocked her out with his slingshot and attempted intercourse. Her booty was too big, like Andre the Giant's...you've seen the statue of David.

Well you heard wrong.

More adultery in the book of fairy tales.

David’s known intimate relationships are with Bathsheba and Jonathan

No he didn't. He and Uriah's wife were in love.
