Ibrani 5:8-9

5:8 Although he was a son, he learned obedience through the things he suffered. ¹  5:9 And by being perfected in this way, he became the source of eternal salvation to all who obey him,

Ibrani 7:25-28

7:25 So he is able to save completely those who come to God through him, because he always lives to intercede for them. 7:26 For it is indeed fitting for us to have such a high priest: holy, innocent, undefiled, separate from sinners, and exalted above the heavens. 7:27 He has no need to do every day what those priests do, to offer sacrifices first for their own sins and then for the sins of the people, since he did this in offering himself once for all. 7:28 For the law appoints as high priests men subject to weakness, ²  but the word of solemn affirmation that came after the law appoints a son made perfect forever.

[5:8]  ¹ sn There is a wordplay in the Greek text between the verbs “learned” (ἔμαθεν, emaqen) and “suffered” (ἔπαθεν, epaqen).

[7:28]  ² sn See Heb 5:2 where this concept was introduced.
