“And deliver them who through fear of death were all their lifetime subject to bondage.”
King James Version (KJV)
2:15 And deliver them, as many as through fear of death were all their lifetime, till then, subject to bondage - Every man who fears death is subject to bondage; is in a slavish, uncomfortable state. And every man fears death, more or less, who knows not Christ: death is unwelcome to him, if he knows what death is. But he delivers all true believers from this bondage.
Heb 2:15 Deliver them. Not only from sin, which gives death its sting (1Co 15:56), but from all "fear of death" by giving the hope of a blessed life to come.
