Ibrani 2:3

2:3 how will we escape if we neglect such a great salvation? It was first communicated through the Lord and was confirmed to us by those who heard him,

Ibrani 10:34

10:34 For in fact you shared the sufferings of those in prison, ¹  and you accepted the confiscation of your belongings with joy, because you knew that you certainly ²  had a better and lasting possession.

[10:34]  ¹ tc Most witnesses, including some important ones (א D² 1881 Ï), read δεσμοῖς μου (desmoi" mou, “my imprisonment”) here, a reading that is probably due to the widespread belief in the early Christian centuries that Paul was the author of Hebrews (cf. Phil 1:7; Col 4:18). It may have been generated by the reading δεσμοῖς without the μου (so Ì⁴⁶ Ψ 104 pc), the force of which is so ambiguous (lit., “you shared the sufferings with the bonds”) as to be virtually nonsensical. Most likely, δεσμοῖς resulted when a scribe made an error in copying δεσμίοις (desmioi"), a reading which makes excellent sense (“[of] those in prison”) and is strongly supported by early and significant witnesses of the Alexandrian and Western texttypes (A D* H 6 33 81 1739 lat sy co). Thus, δεσμίοις best explains the rise of the other readings on both internal and external grounds and is strongly preferred.

[10:34]  ² tn Grk “you yourselves.”
