NET
25 By his treachery he will succeed through deceit. He will have an arrogant attitude, and he will destroy many who are unaware of his schemes. He will rise up against the Prince of princes, yet he will be broken apart—but not by human agency.
Darby
25 And through his cunning shall he cause craft to prosper in his hand; and he will magnify [himself] in his heart, and by prosperity will corrupt many; and he will stand up against the Prince of princes: but he shall be broken without hand.
KJV
25 And through his policy also he shall cause craft to prosper in his hand; and he shall magnify [himself] in his heart, and by peace shall destroy many: he shall also stand up against the Prince of princes; but he shall be broken without hand.
