Betrayal, temptation, and idolatry – linked to the treachery against Samson and Micah's idol.

In Judges 17:2–3, Micah steals 1100 silver pieces from his mother. When he confesses the theft, his mother dedicates the silver to the Lord—but allows it to be used to make a carved image and a cast image, which in practice leads to idolatry in Micah’s private sanctuary. The same amount—1100 silver pieces—is offered by each of the Philistine rulers to Delilah as payment for betraying Samson and revealing the secret behind his strength (Judg 16:5). In both cases, 1100 silver pieces are linked with deceit and faithlessness: Delilah betrays the one closest to her, and Micah’s silver ends up serving idolatry despite being formally dedicated to the Lord. Symbolically, therefore, the number points toward temptation, betrayal, and the religious decline that characterizes the end of the book of Judges.
