{Get thee hence, Satan} (Hupage, Satan(835c)). The words
"behind me" (opis(9320)mou) belong to  Mt 16:23 , not here.
"Begone" Christ says to Satan. This temptation is the limit of
diabolical suggestion and argues for the logical order in
Matthew. "Satan" means the adversary and Christ so terms the
devil here. The third time Jesus quotes Deuteronomy, this time
 De 6:13 , and repels the infamous suggestion by Scripture
quotation. The words "him alone thou shalt serve" need be
recalled today. Jesus will warn men against trying to serve God
and mammon ( Mt 6:24 ). The devil as the lord of the evil world
constantly tries to win men to the service of the world and God.
This is his chief camouflage for destroying a preacher's power
for God. The word here in  Mt 4:10  for serve is latreuseis
from latris a hired servant, one who works for hire, then
render worship.
