Isaiah 7:14:Therefore the Lord himself will give you a sign. Behold, a virgin shall conceive and bear a son, and shall call his name Immanuel.
Luke 1:43:And why is this granted me, that the mother of my Lord should come to me?
Immanuel = “God with us”
The Greek word for *Lord* is not *Theou* (God) but *Kyriou* (Lord)
That verse in Luke proves nothing to support that Elizabeth means *God* when she says *Lord* because she never used the word for God.
