'Mighty' in the Bible

But Zadok the priest, and Benaiah the son of Jehoiada, and Nathan the prophet, and Shimei, and Rei, and the mighty men which belonged to David, were not with Adonijah.

But Nathan the prophet, and Benaiah, and the mighty men, and Solomon his brother, he called not.

And the man Jeroboam was a mighty man of valour: and Solomon seeing the young man that he was industrious, he made him ruler over all the charge of the house of Joseph.
