'Assailant' in the Bible

“But if there is a man who hates his neighbor and lies in wait and ambush for him and attacks him and strikes him down so that he dies, and the assailant escapes to one of these cities,

"If two men are fighting together, and the wife of one comes to rescue her husband from the grasp of his assailant, and she reaches out and seizes his genitals,

“Behold, his [assailant’s] hope and expectation [of defeating Leviathan] is false;Will not one be overwhelmed even at the sight of him?

Although an assailant may overpower one person, two can withstand him. Moreover, a three-stranded cord is not quickly broken.
