Hebrews 2:2-3

2:2 For if the message spoken through angels ¹  proved to be so firm that every violation ²  or disobedience received its just penalty, 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,

[2:2]  ¹ sn The message spoken through angels refers to the OT law, which according to Jewish tradition was mediated to Moses through angels (cf. Deut 33:2; Ps 68:17-18; Acts 7:38, 53; Gal 3:19; and Jub. 1:27, 29; Josephus, Ant. 15.5.3 [15.136]).

[2:2]  ² tn Grk “through angels became valid and every violation.”
