'Mighty' in the Bible

“The bows of the mighty are broken,But those who have stumbled equip themselves with strength.

Woe to us! Who will rescue us from the hand of these mighty gods? These are the gods who struck the Egyptians with all kinds of plagues in the wilderness.

There was a man of [the tribe of] Benjamin whose name was Kish the son of Abiel, the son of Zeror, the son of Becorath, the son of Aphiah, a Benjamite, a mighty man of influence and wealth.

Now the war against the Philistines was severe (brutal, relentless) all the days of Saul; and whenever Saul saw any mighty or courageous man, he recruited him for his staff.

So he ran and stood over the Philistine, grasped his sword and drew it out of its sheath and killed him, and cut off his head with it. When the Philistines saw that their [mighty] champion was dead, they fled.
