Castaway (ἀδόκιμος)

1 Corinthians 9:27; Romans 1:28; 2 Corinthians 13:5-7; 2 Timothy 3:8; Titus 1:16; Hebrews 6:8; Romans 16:10
Paul kept his body under control, lest, though he had preached to others, he himself should be a castaway (1 Cor. 9:2727But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway. (1 Corinthians 9:27)). The same word is translated “reprobate” in Romans 1:2828And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient; (Romans 1:28); 2 Corinthians 13:5-75Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates? 6But I trust that ye shall know that we are not reprobates. 7Now I pray to God that ye do no evil; not that we should appear approved, but that ye should do that which is honest, though we be as reprobates. (2 Corinthians 13:5‑7); 2 Timothy 3:88Now as Jannes and Jambres withstood Moses, so do these also resist the truth: men of corrupt minds, reprobate concerning the faith. (2 Timothy 3:8) and Titus 1:1616They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate. (Titus 1:16); and “rejected” in Hebrews 6:88But that which beareth thorns and briers is rejected, and is nigh unto cursing; whose end is to be burned. (Hebrews 6:8). It is the negative form of “approved” (Rom. 16:1010Salute Apelles approved in Christ. Salute them which are of Aristobulus' household. (Romans 16:10); etc).
