Maybe it will start a fight between Guts and Skull Knight because Guts knows that Skull Knight is collecting behelits for his new sword of resonance, and he kept his for himself. Maybe Skull Knight will cut the Becchi with the sword of resonance creating some portal mumbo-jumbo.
I know the manga sometimes spells it beherit, the movie subs spell it behelit so I think that is the correct spelling. Fan translations really suck sometimes.
