Hebrews 1:5-7

5 For to which of the angels did God ever say, “You are my Son; today I have become your Father”[1]? Or again, “I will be his Father, and he will be my Son”[2]?

6 And again, when God brings his firstborn into the world, he says, “Let all God’s angels worship him.”[3]

7 In speaking of the angels he says, “He makes his angels spirits, and his servants flames of fire.”[4]
