Hebrews 1:9

1:9 You have loved righteousness and hated lawlessness.

So God, your God, has anointed you over your companions ¹  with the oil of rejoicing.” ² 

Hebrews 1:12

1:12 and like a robe you will fold them up

and like a garment ³  they will be changed,

but you are the same and your years will never run out.” ⁴ 

[1:9]  ¹ sn God…has anointed you over your companions. God’s anointing gives the son a superior position and authority over his fellows.

[1:9]  ² sn A quotation from Ps 45:6-7.

[1:12]  ³ tc The words “like a garment” (ὡς ἱμάτιον, Jw" Jimation) are found in excellent and early mss (Ì⁴⁶ א A B D* 1739) though absent in a majority of witnesses (D¹ Ψ 0243 0278 33 1881 Ï lat sy bo). Although it is possible that longer reading was produced by overzealous scribes who wanted to underscore the frailty of creation, it is much more likely that the shorter reading was produced by scribes who wanted to conform the wording to that of Ps 102:26 (101:27 LXX), which here lacks the second “like a garment.” Both external and internal considerations decidedly favor the longer reading, and point to the author of Hebrews as the one underscoring the difference between the Son and creation.
