Hebrews 5:4

5:4 And no one assumes this honor ¹  on his own initiative, ²  but only when called to it by God, ³  as in fact Aaron was.

Hebrews 4:2

4:2 For we had good news proclaimed to us just as they did. But the message they heard did them no good, since they did not join in ⁴  with those who heard it in faith. ⁵ 

[5:4]  ¹ sn Honor refers here to the honor of the high priesthood.

[5:4]  ² tn Grk “by himself, on his own.”

[5:4]  ³ tn Grk “being called by God.”

[4:2]  ⁴ tn Or “they were not united.”

[4:2]  ⁵ tc A few mss (א and a few versional witnesses) have the nominative singular participle συγκεκερασμένος (sunkekerasmeno", “since it [the message] was not combined with faith by those who heard it”), a reading that refers back to the ὁ λόγος (Jo logo", “the message”). There are a few other variants here (e.g., συγκεκεραμμένοι [sunkekerammenoi] in 104, συγκεκεραμένους [sunkekeramenou"] in 1881 Ï), but the accusative plural participle συγκεκερασμένους (sunkekerasmenou"), found in Ì^13vid,46 A B C D* Ψ 0243 0278 33 81 1739 2464 pc, has by far the best external credentials. This participle agrees with the previous ἐκείνους (ekeinou", “those”), a more difficult construction grammatically than the nominative singular. Thus, both on external and internal grounds, συγκεκερασμένους is preferred.
