Hebrews 2:16-18 For verily he took not on him the nature of angels; but he took on him the seed of Abraham. Wherefore in all things it behoved him to be made like unto his brethren, that he might be a merciful and faithful high priest in things pertaining to God, to make reconciliation for the sins of the people. For in that he himself had suffered being tempted, he is able to succour them that are tempted. 

‘For verily he took not on him the nature of angels; but he took on him the seed of Abraham.’ Here Paul sums up his argument about Christ being better than angels, declaring He did not take on the nature of angels, but became the natural seed of Abraham. He needed to be made in all things like unto His brethren “that He might be a merciful and faithful high priest” in the things of God, to remit their sins by His own atonement, and to represent them in time of temptation (2:17-18). Thus, Paul shows the Jews that Christ had to be made a human being; that He came from Abraham according to the flesh; that He was one of their own people; that redemption could not have been possible otherwise; that the Messiah had to suffer to redeem; and that He is now able to help and deliver all men who are tempted.
