Proverbs 18:17-19

Complete Jewish Bible

¹⁷ The first to state his case seems right,
    till the other one comes and cross-examines.
¹⁸ Casting lots puts an end to strife
    and separates powerful disputants.

¹⁹ It is harder to win an offended brother than a strong city;
    their fights are like the bars of a fortress.
