lit., "a meeting together with, a coincidence of circumstances, a happening," is translated "chance" in Luke 10:31 . But concurrence of events is what the word signifies, rather than chance.
Note: Some texts have tucha here (from tunchano, "to happen").lit., "if it may happen" (ei, "if," tunchano, "to happen"), signifies "it may chance," 1 Corinthians 15:37 .
