fred'-man, fre'-man: The term occurs in 1Co 7:22; Col 3:11, and Re 6:15, and represents two slightly different words. In 1Co 7:22 the word is apeleutheros, "a freeman," one who was born a slave and has received freedom. In this case it refers to spiritual freedom. He that was in bondage to sin has been presented with spiritual freedom by the Lord. In Re 6:15 the word is simply eleutheros, "a free man" as opposed to a slave.
