Castaway kast'-a-wa (adokimos, from dokimazo, "I test," "I approve after testing," hence, approved after being tested): This word is rendered "castaway" only in the King James Version: "I myself should be a castaway" ("rejected" the Revised Version (British and American), the American Standard Revised Version, 1 Corinthians 9:27). but the same word occurs a number of times usually translated "reprobate" (Romans 1:28, 2 Corinthians 13:5-7, 2 Timothy 3:8, Titus 1:16); "rejected" (Hebrews 6:8).
