From the early Church Fathers to now.
“And there were found of Benjamin five and twenty thousand men that drew the sword, besides the inhabitants of Gabaa,”
“And when at first the people of Israel were defeated, yet unmoved by fear at the reverses of the war, they disregarded the sorrow the avenging of chastity cost them. They rushed into the battle ready to wash out with their own blood the stains of the crime that had been committed.”
“In the first and second encounters, when many were harmed by a few, the Israelites considered yielding, since the battles were so unfavorable. There were four hundred thousand men warring against twenty-five thousand of the tribe of Benjamin, and they strove with seven hundred Gabanites [Gibeonites] experienced in war. When two battles were unfavorable, Israel with eager spirit did not lose hope of victory nor of vengeance for the hope they had fostered. Superior in cause and number they yet fell back defeated in the battle's outcome, and, feeling that God was offended, they tried with fasting and much weeping to gain a reconciliation of heaven's favor.”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
