Hebrews 2:5-13 discusses humanity's role in creation and Jesus' accomplishment on the cross. It references Psalm 8, where God made humanity to rule over creation but be slightly lower than angels. Jesus was made temporarily lower than angels and suffered death so that through God's grace he could experience death for all people. By bringing many to salvation, God made Jesus the perfect author of salvation. Both Jesus and those he saves are part of the same family, and he is not ashamed to call believers his brothers.
