6:10 died unto sin once. The Greek ephipaz, translated “once” here, actually means “only once” or “once for all.” It is used just four other times, always with this specific meaning. “Five hundred brethren” saw the resurrected Christ “at once” (I Corinthians 15:6). We are sanctified through the offering of the “body of Jesus Christ once for all” (Hebrews 10:10). See also Hebrews 7:27; 9:12.
