Easton's Bible Dictionary (1897)
That which is rejected on account of its own worthlessness (Jer. 6:30; Heb. 6:8; Gr. adokimos, “rejected”). This word is also used with reference to persons cast away or rejected because they have failed to make use of opportunities offered them (1 Cor. 9:27; 2 Cor. 13:5-7).
