Luke 18:3 describes a widow in a city who repeatedly approaches a judge, asking him to give her justice against someone who is opposing her. The verse highlights her persistence and her plea for help in a situation where she feels wronged.
In this part of Jesus’ parable, the widow is a character who represents someone vulnerable and without power, since widows in that society often had little protection or support. She comes to the judge, who is known for being unjust, and asks him to “avenge” her, meaning to grant her justice or defend her rights against her adversary. This sets the stage for Jesus’ teaching about persistence in seeking justice or help, especially from someone in authority.
