Hebrews 1:6 - "...and when again He may bring in the first-born to the world, He saith, 'And let them bow before him -- all messengers of God." (YLT)
Many Bible translators appear to have a penchant for inserting the word "worship" whenever the Greek word προσκυνέω appears. (Proskyneō)
Definition: Proskyneō - in the NT by kneeling or prostration to do homage (to one) or make obeisance, whether in order to express respect or to make supplication, used of homage shown to men and beings of superior rank.
The NWT does it as well:
(Revelation 19:10) "At that I fell down before his feet to worship him. But he tells me: “Be careful! Do not do that! I am only a fellow slave of you and of your brothers who have the work of witnessing concerning Jesus."
(Revelation 22:8) "Well I, John, was the one hearing and seeing these things. When I heard and saw them, I fell down to worship at the feet of the angel who had been showing me these things."
Are we to believe that an apostle of Christ would try to worship an angel - twice???????? Or was he trying to exhibit -
Obeisance - a movement of the body expressing deep respect or deferential courtesy, as before a superior; a bow, curtsy, or other similar gesture.
