David was never described as an ‘abomination of desolation’.
Solomon also sold his soul for a golden tribute of 666 talents per year.
David also lived in misery after he “moved” Uriah to the front lines after David failed to convince Uriah to come back and have relations with Bathsheba to cover up an adulterous pregnancy.
God took away (Died at an young age) David’s first born of Bathsheba as a punishment for Uriah and then David’s oldest son Amnon raped David’s daughter Tamar (Amnon half-sister, lol). To make matters worse, David’s son Absalom ran a train on his dad’s concubines and several of David’s wives. Then started a civil war against his dad.
Why do people think God did not have justice for Uriah? God is perfect in justice, love, and forgiveness. He dispenses all and David, although spiritually forgiven because he repented and accepted his misery that caused was humble for it.
Also the only reason God let David stay married to Bathsheba was because Uriah was dead. Had Uriah lived, David was in line to face the punishment for adultery. God pretty much made David’s life a living hell because justice called for that. The people of Israel suffered due to David’s sin.
David’s son Nathan, the most humble and Spiritual one is where the line of Mary came from.
Is the Messiah a Descendant of King Solomon?
The broader issue that should be pondered, though, is how can this be proven without any doubt, close to 3000 years down the line?
A positive identification of the Messiah, directly from Solomon. How to know? It's mysteries of the universe-level stuff. It's one of those things where it follows that
"And ye shall know that I am the Lord."
Watch it come right out of a place noone would think to look. Seems to be a pattern going on with that.
