Hebrews 2:14-15

Therefore, since [these His] children share in flesh and blood [the physical nature of mankind], He Himself in a similar manner also shared in the same [physical nature, but without sin], so that through [experiencing] death He might make powerless (ineffective, impotent) him who had the power of death—that is, the devil— and [that He] might free all those who through [the haunting] fear of death were held in slavery throughout their lives.
