Judges 21:7

‘ How shall we do for wives for those who remain, seeing we have sworn by Yahweh that we will not give of our daughters to be their wives.?'

They had decided on mercy for the six hundred holed up in the Rock, but the problem now was how to find wives for them without breaking their solemn oath to Yahweh. It is a reminder that we do well to consider carefully before we make promises and take oaths. They are not easily undone. But as such men will they had a solution. Men are always good at wriggling out of inconvenient promises.
