2Co 13:5

FAIL THE TEST: The word “adokimos” is translated “reprobate” (Rom 1:28; 2Co 13:5-7, 2Ti 3:8; Tit 1:16), “castaway” (1Co 9:27), and “rejected” (Heb 6:8). It is used to describe a counterfeit coin, deficient as to weight or quality of metal. It is also used, figuratively, to describe a cowardly soldier who fails the test of battle; a candidate rejected for office; and a stone rejected by the builders. In each case, that which is “reprobate” has promised something by its outward appearance which it cannot deliver! It has, perhaps, a “name to live”, but it is dead — like clouds that promise rain, but give none; like stars in the heavens that appear fixed, but prove to be “wandering stars”, or meteors.

2Co 13:11
