For in bringing many sons to glory, it was only fitting that God, the Creator and Preserver of everything, should bring the Initiator of their deliverance to the goal through sufferings.
For both Yeshua, who sets people apart for God, and the ones being set apart have a common origin - this is why he is not ashamed to call them brothers
when he says, "I will proclaim your name to my brothers; in the midst of the congregation I will sing your praise."
Also, "I will put my trust in him, . . ." and then it goes on, "Here I am, along with the children God has given me."
Therefore, since the children share a common physical nature as human beings, he became like them and shared that same human nature; so that by his death he might render ineffective the one who had power over death (that is, the Adversary)
and thus set free those who had been in bondage all their lives because of their fear of death.
Indeed, it is obvious that he does not take hold of angels to help them; on the contrary, "He takes hold of the seed of Avraham."
This is why he had to become like his brothers in every respect - so that he might become a merciful and faithful cohen gadol in the service of God, making a kapparah for the sins of the people.
For since he himself suffered death when he was put to the test, he is able to help those who are being tested now.
