Hebrews 2:11-13

11Both the one who makes people holy and those who are made holy are of the same family. So Jesus is not ashamed to call them brothers and sisters. The Greek word for brothers and sisters (adelphoi) refers here to believers, both men and women, as part of God’s family; also in verse 12; and in 3:1, 12; 10:19; 13:22.

12He says, “I will declare your name to my brothers and sisters; in the assembly I will sing your praises.” Psalm 22:22

13And again, “I will put my trust in him.” Isaiah 8:17 And again he says, “Here am I, and the children God has given me.” Isaiah 8:18
