Bible History of David and Edom Accurate

Critics have long sought to discredit the Biblical account of King David but archaeologists have vindicated it on two fronts. 


First of all did  King David actually exist  or is this just a piece of Biblical mythology as some claim?  Before  there was little or no proof outside of the Bible itself that he did actually exist.


In 1993, however, archaeologists discovered a basalt stone in northern Israel from the ninth century B.C.E. On it they read the words:  "House of David" and "kings of Israel".  Proof of his existence apart from the Biblical account.


Now, what  about Biblical accounts such as 2 Samuel 8: 13, 14 describing battles with  Edom? Until recently critics claimed that Edom during the reign of David was just a small pastoral society that could not possibly threaten David and Israel.


 Now, however, according  to the Biblical Archaeological Review fairly recent discoveries  have proved that Edom  was indeed a very complex society centuries earlier than critics have claimed. And could have been a serious threat to David's Israel as described in the Bible. 


So the Biblical accounts of  David's existence and battles with the Edom are accurate
