Judges 19:22: [Now] as they were making their hearts merry, behold, the men of the city, certain sons of Belial, beset the house round about, [and] beat at the door, and spake to the master of the house, the old man, saying, Bring forth the man that came into thine house, that we may know him.
Contradiction with Judges 19:25
In this verse, the host is unable to prevent the abuse of his guest, contradicting the initial promise of no lack of anything made in Judges 19:20.
Judges 19:25: But the men would not hearken to him: so the man took his concubine, and brought her forth unto them; and they knew her, and abused her all the night until the morning: and when the day began to spring, they let her go.
Contradiction with Judges 19:21
This verse, immediately following Judges 19:20, shows the host providing for the guest's needs, which seems consistent, yet it contrasts with the subsequent tragic events, implying a lack of true safety and comfort.
Judges 19:21: So he brought him into his house, and gave provender unto the asses: and they washed their feet, and did eat and drink.
