The sons of Benjamin are preserved (Judges 20:27b-28; 21:1, 21:6)

Phinehas the priest prayed, "Our LORD, the people of Benjamin are our relatives. Should we stop fighting or attach them?" "Attach!" the LORD answered. "Tomorrow I will let you defeat them." When the Israelites had met at Mizpah before the war with Benjamin, they had made this sacred promise: "None of us will ever let our daughter marry a man from Benjamin." The Israelites were sad about what had happened to the Benjamin tribe, and they said, "one of our tribes was almost wiped out."

The background to this dispute is that a Levite concubine had been murdered in the land of Benjamin and the brother tribes considered them to be a reproach and for the sake of moral purity they set their faces against their brother. The sons of Benjamin are known to be valient warriers. They handled their own against the other tribes until God gave them over to the other sons of Israel. We have learned in earlier lessons the grave danger of making an oath in the LORD's name. Here, with little thought, they vow to withhold wives from the sons of Benjamin not considering that this brother's inheritance will be extinguished if they uphold such a pledge.
Their remedy in this instance is that they found Jews who were not present at the assembly when the vow was made and gave their virgin daughters to Benjamin so that Benjamin would be preserved. God gave his approval to this civil war because he did not want unholy living to be present among his people.

Daily Prayer: Father, it is better to have my discipline fall into the hands of a merciful God than into the hands of men. I know that God does not withhold discipline from his sons and daughters because this is his mark of love for those he calls his own. Let me learn to be careful with my words, especially when they are made as a promise or a vow. Instead, let my yes be yes and my no be no. In your name I pray Amen.
