Hebrews 2:11
Nestle 1904 Greek New Testament · Berean Standard Bible
ὅ τε γὰρ ἁγιάζων καὶ οἱ ἁγιαζόμενοι ἐξ ἑνὸς πάντες δι’ ἣν αἰτίαν οὐκ ἐπαισχύνεται ἀδελφοὺς αὐτοὺς καλεῖν
For both the One who sanctifies and those who are sanctified are of the same family. So Jesus is not ashamed to call them brothers.
