From Hebrews 2
But we see Jesus, who was made a little lower than the angels, now crowned with glory and honour because he suffered death, so that by the grace of God he might taste death for everyone.
Since the children have flesh and blood, he too shared in their humanity so that by his death he might destroy him who holds the power of death--that is, the devil--
and free those who all their lives were held in slavery by their fear of death.
