In 1 Samuel 20:30.. Is Saul saying: "SON of a *****?"? After reading those verses from 1 sam 20:1-30, it seems like Saul is actually Screaming: You "SON of a *****?"?... but the Bible writers or translators seems to polish that verse with seemingly "Polite" words... by saying things like son of a rebellious woman etc...
According to BibleHub.com's "Hebrew Text Analysis Page", the Hebrew text is 


  בֶּֽן־נַעֲוַ֖תהַמַּרְדּ֑וּתהֲל֣וֹאיָדַ֗עְתִּי


and a literal translation is something along the lines of


  son of the perverse rebellious [woman]


Thus it appears that this is what Saul in fact did say, although he may have meant, as the New Living Translation has it,


  You son of a whore!


or as the New English Translation (NET Bible) says,


  You stupid traitor!


The Douay-Rheims Bible seems to be getting at the same thing the NLT wants to say, though in 16th-century language:


  Thou son of a woman that is the ravisher of a man!


But though Saul may have meant this, there's no indication that he actually said it.
