'Mighty men' in the Bible

And David heard. And he sent Joab and all the army of the mighty men.

And he threw stones at David and at all the servants of King David. And all the people and all the mighty men were on his right hand, and on his left.

For, Hushai said, you know your father and his men, that they are mighty men, and they are bitter of soul, like a bear robbed of her cubs in the field. And your father is a man of war, and will not stay the night with the people.

And also he, the son of valor, whose heart is like the heart of a lion, shall utterly melt. For all Israel knows that your father is a mighty man, and they who are with him are mighty men.

And Joab's men went out after him, and the Cherethites, and the Pelethites, and all the mighty men. And they went out of Jerusalem to pursue Sheba the son of Bichri.

These are the names of the mighty men whom David had: Josheb-basshebeth the Tachmonite, chief of the three; he was called Adino the Eznite, because of the eight hundred he killed at one time.

And after him was Eleazar the son of Dodo the Ahohite, one of the three mighty men with David when they defied the Philistines who were gathered there to battle; and the men of Israel had gone up;

And the three mighty men broke through the army of the Philistines, and drew water out of the well of Bethlehem by the gate, and took it, and brought it to David. But he would not drink of it, but poured it out to Jehovah.

And he said, Be it far from me, O Jehovah, that I should do this. Is it not the blood of the men who went in danger of their lives? And he would not drink it. These three mighty men did these things.
