Hebrews 2:13-15 And again, I will put my trust in him. And again, Behold I and the children which God had given me. Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil; And deliver them who through fear of death were all their lifetime subject to bondage. 

‘I will put my trust in him.’ This is the 9th Old Testament prophecy in Hebrews (2:13; 2Sam. 22:3) and is fulfilled. From 2Samuel 22 and Psalms 18, we have twelve things that God is to His people: Rock (2Sam. 22:2, 3, 29, 31, 32, 33, 40; Ps. 18:2). Fortress. Deliverer. God of my Rock. Shield. The horn of my salvation. High tower. Refuge. Saviour. Lamp. Buckler. Strength.

‘Behold I and the children which God had given me.’ This is the 10th Old Testament prophecy in Hebrews (2:13; Isa. 8:18) that is fulfilled.

‘Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil.’ Seeing that those whom He represents are flesh and blood, it was necessary for Him also to become flesh and blood that He might be capable of dying in their place, by this act of destroying satan and annulling his power of death over mankind.

‘And deliver them who through fear of death were all their lifetime subject to bondage.’ This refers to the deliverance of all righteous souls from the captivity of satan and their prison in the lower parts of the earth. Christ descended first into hell (Ps. 16:10; Acts 2:27), in the lower parts of the earth (Eph. 4:8-10; Matt. 12:40), then captured the righteous souls from satan, leading them captive to heaven when He ascended on high as referred to in Ephesians 4:8-10. This fulfilled Psalm 68:18. Before this, all righteous souls went into hades or sheol, along with the souls of the wicked, but in another compartment with a great gulf between them (Luke 16:19-31). Now, the souls of the righteous no longer go into the heart of the earth to be held captive against their will. They go immediately to paradise at physical death to await the resurrection of their bodies (2Cor. 5:8; Php. 1:21-24). The wicked continue to go to the torment compartment of Hades or Sheol and will continue to do so until the end of the Millennium. Then death and Hades will deliver up the wicked souls who will be united with their bodies in the resurrection to be judged and sent to eternal hell (Rev. 20:11-15).
