Ibrani 1:3

1:3 The Son is ¹  the radiance of his glory and the representation of his essence, and he sustains all things by his powerful word, ²  and so when he had accomplished cleansing for sins, he sat down at the right hand of the Majesty on high. ³ 

Ibrani 13:21

13:21 equip you with every good thing to do his will, working in us ⁴  what is pleasing before him through Jesus Christ, to whom be glory forever. ⁵  Amen.

[1:3]  ¹ tn Grk “who being…and sustaining.” Heb 1:1-4 form one skillfully composed sentence in Greek, but it must be broken into shorter segments to correspond to contemporary English usage, which does not allow for sentences of this length and complexity.

[1:3]  ² tn Grk “by the word of his power.”

[1:3]  ³ sn An allusion to Ps 110:1, quoted often in Hebrews.

[13:21]  ⁴ tc Some mss (C P Ψ 6 629* 630 1505 pm latt sy^h) read ὑμῖν (Jumin, “in you”) here, but ἡμῖν (Jhmin) has stronger external support (Ì⁴⁶ א A D^vid K 0243 0285 33 81 104 326 365 629^c 1175 1739 1881 pm sy^p co). It is also more likely that ἡμῖν would have been changed to ὑμῖν in light of the “you” which occurs at the beginning of the verse than vice versa.

[13:21]  ⁵ tc ‡ Most mss (א A [C*] 0243 0285 33 1739 1881 Ï latt) include the words “and ever” here, but the shorter reading (supported by Ì⁴⁶ C³ D Ψ 6 104 365 1505 al) is preferred on internal grounds. It seemed more likely that scribes would assimilate the wording to the common NT doxological expression “for ever and ever,” found especially in the Apocalypse (cf., e.g., 1 Tim 1:17; 2 Tim 4:18; Rev 4:9; 22:5) than to the “forever” of Heb 13:8. Nevertheless, a decision is difficult here. NA²⁷ places the phrase in brackets, indicating doubts as to its authenticity.
