'Mighty men' in the Bible

“Their quiver is [filled with the dead] like an open grave;They are all mighty men [heroes of their nation].

And when Jehoiakim the king, with all his mighty men and all the princes, heard his words, the king sought to put Uriah to death; but when Uriah heard of it, he was afraid and fled and escaped to Egypt.

“How can you say, ‘We are great warriorsAnd valiant men in war?’
