Hebrews 1:6-8

Heb 1:6-8 And again, when he bringeth in the first begotten into the world, he saith, And let all the angels of God worship him. And of the angels he saith, Who maketh his angels spirits, and his ministers a flame of fire. But unto the Son [he saith], Thy throne, O God, [is] for ever and ever: a sceptre of righteousness [is] the sceptre of thy kingdom.

In the Blank Bible Edwards comments on verse 6:

Again when he bringeth…] The Apostle has probably here some reference to the 97th Psalm where we have a prophecy of the Messiah's coming into the world on which occasion it is said verse 7 worship him all ye gods. But fact or event (in which that prophecy was fulfilled) was what was at Christ's birth that we have some intimation in the second chapter of Luke where we are told that on the occasion there appeared a multitude of the Heavenly Hosts singing, Glory to God in the highest…. - at that time when the Son of God appeared a poor little infant in a stable and manger then God said Let all the angels of God worship Him and then the Angels had a great trial of their obedience greater than ever they had before.

This last remark may seem surprising. According to Edwards the fall of the angels occurred when announcement was made that they were to be the ministering servants of men's salvation. The angels who survived that "great trial of obedience" were established forever as good angels. That Christ's later being born as a man "in a stable and manger" could have been a "trial" at all, not to mention "greater than ever they had before" may seem inconsistent. The explanation may be that, although the angels were established, they could be tempted as Jesus was, and the saints are in this world, at least. Promised preservation and perseverance does not precede testing or imply a possibility of failing.

Speaking of Christ, Edwards remarks:

[I]n Jesus Christ, who is both God and man, those two diverse excellencies are sweetly united. He is a person infinitely exalted in glory and dignity. Php_2:6. "Being in the form of God, he thought it not robbery to be equal with God." There is equal honor due to him with the Father. John 5:23 - "That all men should honor the Son, even as they honor the Father." God himself says so to him, "Thy throne, O God, is forever and ever," Hebrews 1:8. And there is the same supreme respect and divine worship paid to him by the angels of heaven, as to God the Father, (Hebrews 1:6) "Let all the angels of God worship him." Heb. 1:9
