'Stout' in the Bible

Wherefore it shall come to pass, that, when the Lord hath performed his whole work upon mount Zion and on Jerusalem, I will punish the fruit of the stout heart of the king of Assyria, and the glory of his high looks.

and concerning the ten horns that were on its head, and the other horn which came up, and before which three fell, even that horn that had eyes, and a mouth that spake great things, whose look was more stout than its fellows.

Your words have been stout against me, saith Jehovah. Yet ye say, What have we spoken against thee?
