Hebrews 2:7

You made him lower than the angels for a little while. You crowned him with glory and honor. ¹ 

Heb 2:9

¹ tc Several witnesses, many of them early and important (א A C D* P Ψ 0243 0278 33 1739 1881 al lat co), have at the end of v 7, “You have given him dominion over the works of your hands.” Other mss, not quite as impressive in weight, lack the words (Ì⁴⁶ B D² Ï). In spite of the impressive external evidence for the longer reading, it is most likely a scribal addition to conform the text of Hebrews to Ps 8:6 (8:7 LXX). Conformity of a NT quotation of the OT to the LXX was a routine scribal activity, and can hardly be in doubt here as to the cause of the longer reading.
