'Prosper' in the Bible

Because of the transgression, the Heavenly Army will be given over, along with the regular burnt offering, and in that rebellion truth will be cast to the ground, while he continues to prosper and to act."

Through his skill he'll cause deceit to prosper under his leadership. He'll promote himself and will destroy many while they are secure. He'll take a stand against the Prince of Princes, yet he'll be crushed without human help.
