'Mighty men' in the Bible

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

And he cast 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, said Hushai, you know your father and his men, that they are mighty men, and they are chafed in their minds, as a bear robbed of her whelps in the field: and your father is a man of war, and will not lodge with the people.

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

These are the names of the mighty men whom David had: The Tachmonite that sat in the seat, chief among the captains; the same was Adino the Eznite: he lifted up his spear against eight hundred, whom he slew 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 that were there gathered together to battle, and the men of Israel had gone away:

And the three mighty men broke through the host of the Philistines, and drew water out of the well of Bethlehem, that was by the gate, and took it, and brought it to David: nevertheless he would not drink it, but poured it out unto the LORD.

And he said, Be it far from me, O LORD, that I should do this: is not this the blood of the men that went in jeopardy of their lives? therefore he would not drink it. These things did these three mighty men.

These things did Benaiah the son of Jehoiada, and won a name among three mighty men.
