Luk 4:8 Get thee behind me, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve.
Go away opposition! For it has been recorded: "To Master, that God of yours, you shall bow down and to him only alone are you going to be serve prayers.
Again, the King James Version is a copy of Mat 4:10, but the Greek source we used today doesn't include the first phrase. There is also a difference in order. In Matthew's account, this is the final temptation, not the second.
And, again, referring back to the previous verse, Mat 4:4, though "it is written," is translated in the present tense in the KJV, the Greek is in a form where the action is completed in the past.
"Thou shall worship" is from a Greek word that means "make obeisance", specifically to prostrate yourself before authority, as we would use the Chinese term, "kowtow."
The word translated as "Lord," is the same as the one used to describe a master of slaves. While most references to slaves in the KJV are translated to "servants," the use of "Lord" and "slaves" is common in Christ's parables because it describes a common employment situation of his time.
The word translated as "God" means "God" and "diety." It is introduced with an article, so "the God." Christ often uses it this way perhaps to indicate the one God as opposed to the pagan gods.
The primary meaning of the Greek word translated as "serve" is "to work for hire," but its secondary meaning is "to be enslaved to." The "to serve" translation is more generic, though it fits well with the general translation of of "slave" into "servant."
Together, these three images, a master, people kowtowing, and being enslaved, create a strong sense of humbling yourself before God. This is a much stronger image in Greek than the KJV translation version.
