Judges 21:5 refers to the assembly of the tribes of Israel, which is first mentioned in Judges 20:1. This connection underscores the unity and collective action of Israel in addressing the crisis with the tribe of Benjamin.

Judges 21:25 repeats the refrain that 'everyone did what was right in his own eyes,' which is also found in Judges 17:6. This highlights the theme of moral and spiritual chaos in Israel during the time of the judges.
